So the actual stiffness increase when going from 0.88 bar to 0.92 bar is almost 20 % not the 5% as you used in your approximations for the front end handling vs weight decrease.
Thank you for the correction!!!   Sounds like the 0.88 bars won't be near stiff enough.  Thats good to know.

Routed hyd brake line and park cable.  Only added a couple of bends to brake line and ran it thru existing holes in trany Xmember just outboard of where my subframe connectors blocked off the original hole.  Park brake cable rides "high" but works fine.  Want to see how park cable fits with trany and exhaust before changing where its at now.
For gas tank vent decided to skip the charcoal canister, but keep the vapor separator.  So routed the vap sep to lower frame rail ahead of rear wheel sort of like early challenger vent that went into frame rail.   I think I'll install the 1974 OEM pressure/vacuum valve between the vap sep and my home-made tubing.
Tried to make my own 3/8 fuel line from brake tubing, but the metal tubing was too stiff for my cheapie tube bender.  Was slightly crushing the tubing, so the cross section area of the tube might not be any better than the 5/16 that was OEM.  So ordered 3/8 fuel line and 1/4 fuel return line from Inlinetubing.  They were recommended by several folks on this forum.
On my old Ford truck I liked how clean an HEI distributor was compared to all the wires for OEM Ford duraspark elec ignition, and the HEI actually starts faster.  So decided to do the same on the Mopar 360.  I looked at DUI ignition, called them, but their distributor has a long housing, was afraid it would hit the air cleaner or such.   So bought a Proform HEI.  Here is the fit check with carb and air cleaner.  No issues.
Decided to change from KB hyper pistons to Ross forged.  So crank and other parts are being balanced.   If someone is looking for a set of new in box never run KB hyper pistons with pins, keepers, and moly rings 0.030 over for a 360 send me a PM.  I'll post them for sale at some point.  Price will be discounted just to move them.

I guess they delete my recent pictures because I dont mind changing grilles, and didnt follow the mopar ignition system to the letter.  Maybe what I'm doing is just not exciting enough.  whatever
Thanks for all your help answering my questions. 
Finished the heater box.  Added new heater core. Took the blower motor apart, one of the brush wires was almost cut apart by rubbing against the armature.  Shortened the wire a bit and soldered it back together.  Polished the armature where the brushes contact with 600 grit, and added a touch of wheel bearing grease to the two bushings.  Motor runs great.   Was able to remove the passenger side fresh air door by drilling out the rivets, then going back together I used a #8 x 3/8 bolt with washers and locktite nut.  Ground head down to clear fresh air door.  Works great.  Thats bug screen at the fresh air opening.  We have hornets real bad here.  They make nests everywhere, so I'm trying to keep them out of the Challenger.
The detroit muscle tech heater gasket kit was first rate, and definitely use the 3M high strength spray adhesive, part number ends with "90".  Its not too thin, bonds well but also lays on top of the foam, insulation, etc.  Put the factory firewall insulation in, no fatmat or quietmat...just too much more money at this point.
Added a Hellwig 1.125 diameter front sway bar.  I previously welded a hemi/6 pak skid plate to the bottom of the K-frame, and the larger sway bar had to be persuaded into position.  This took some of the nice finish off the bar in a couple places.  On the links between sway bar and lower control arm I shortened the hollow tube spacers about 3/8 inch, so the complete bushing set could be attached with no weight on the front suspension.  I'm going to try the 0.92 diameter torsion bars, should work fairly well with light weight small block engine.  Don't really want too stiff a ride, and the car won't be autocrossed.
I installed the in-line-tubing company 3/8 fuel line with 1/4 return line.  Nice product but the bends in the return line made it install both above and below the fuel line near the rear axle.  I would have expected each line to stay on one side or the other.  Guess I'm expecting too much.
Had the brake booster rebuilt by power brake booster exchange in Portland OR.  Good communication, quick turn around.  They said the plating was OEM, but for me was a little rough so I clear coated it with rattle can engine clear so in the future I can wipe it down easily.  The clear coat made the color shift to a little more gold.
My brake master cylinder has pitting in the cylinder bore, so needs sleeved.  On this forum Brakeplace.com was recommended so eventually I'll send it there.   Looked for replacement master cylinder.  I saw discussion on this forum about the new aluminum replacement master cylinders, but decided to stay OEM.  Went to a couple parts houses, they had the type with the square front resevoir that needs fitting adapters to hook the lines up.  Finally went to carquest and there was the correct master cylinder with curved front resevoir.  It had been sleeved with cast iron, but was missing the retaining screw for the rear brake piston.  Don't know how important it is, but since it was there OEM I made one from a 10-24NC x 1/2 inch long machine screw.  Had to drill the hole for this screw thru the sleeve which left a burr inside the cylinder.  Ran the little wheel cylinder hone thru it advancing the hone slowly to not leave a crosshatch...then wrapped fine grit steel wool #0000 around the hone and polished the bore.  Used dot5 brake fluid during the honing operations since thats what I'll be running in the system, but use whatever fluid you'll be running and don't clean the cylinder with solvent...I cleaned with brake clean from spray can.   Did not paint the master cylinder since they aren't painted from the factory for 71 and up I believe.
The brake pedal is lower than the clutch pedal, with clutch pedal up against its rubber stop.  I asked on this forum, they said this is the way it is for power brake setup.  I'm used to having both clutch and brake pedals the same height off the floor.  I'll look around maybe find a longer link between brake pedal and pivot linkage assy.  Dont want to make one as this is safety critical part.  I'll give it some more thought.
On a side note I'm putting together an old Datsun 210, EPA rated at 50 mpg.  I know I can reach at least 55 mpg with compression increase and other detail engine work.  Its all interesting to me.

Love your work, Phil, and your explanations.  Top notch work.

Don't be offended about your pics disappearing - the uploader gets full quickly and Ross (69ChargerR/T - the list owner) has to go in and clean out old photos on a regular basis.  Most of my pics on my resto thread are long gone.  The only way to keep them from disappearing are to use a photo hosting site like Photobucket or Imageshack and then link to the picture.  :2thumbs:

Finished battery in trunk and added trunk ballast.  I have a CAT battery in the old work truck that is at least 17 years old and still works great.  I figure CAT is perfect for vehicles that don't get used much...just like heavy equipment that sits around then needs to start without hassle.
CAT makes stock size batteries, but I chose to sort of copy the 60's Mopar super stock with an extra large trunk mounted battery for extra weight, a Caterpillar "small" schoolbus battery #115-2422 with 1000 cold crank amps that measures 13x7x9.5 height and weighs 58 lb.  I mounted the battery directly over the rear frame rail to give it as much support as possible.  Some of the super stockers added a skid plate over the gas tank for extra weight, but I chose to go a different route.
Other parts include: Summit 2 gauge cable kit #SUM-G1220A, Taylor battery box #TAY-48100, Moroso 2 gauge cable ends #MOR-74170, Longacre bulkhead connector #LNG-45700 to connect cables thru firewall, and HellaMarine battery cut off switch #HLA-2843 which is waterproof, has removable key, and is good for 100 amps continuous current.
I located the bulkhead connector in the firewall hole for the windshield foot pump.  Was hard to get it tightened to my liking but otherwise location is good.
The support plate for the battery is steel sheet stock 15x10x1/4 thick, and with thick bar stock to make the plate "level", the complete plate weighs 14 lb.  I added a steel plate to the trunk floor, it is sheet stock 29x19x3/8 thick and weighs 53 lb.  This plate has 1/4 thick spacers welded at each bolt thru location to lift the plate off the OEM sheet metal to allow for the not-very-flat OEM trunk floor.  On the underside of the factory sheet metal at each bolt location I backed up the sheet metal with thick fender washers to spread out the clamping force so there's thick metal above and below the thin sheet metal at each bolt/nut.
So total weight added to trunk is 58+14+53=125 lb.  Now include weight removal from engine compartment: 2 alum cyl heads=50 lb, alum intake manifold=20 lb, remove OEM battery=45 lb for total removed=115 lb.   So the total weight shifted to the trunk is 125+115=240 lb.  Not too shabby.  I did not include getting rid of the 5mph front bumper, and I'll be using power steering so I'm not going for every ounce.  I look forward to weighing the finished car to see how much weight is on each wheel.   I'd like to have only 55% of the total vehicle weight on the front wheels, and less would be even better. 
Car should then have great rear wheel traction and good cornering/handling too....real good for street use.

The RC Auto Body in BigTimber did a hack job fitting everything, for instance neither the tail lights/rear trim or the headlite bezels fit correctly or at all...even though I had given him all these pieces to fit check.  It takes a craftsman to pay attention to the details to get these parts to fit correctly.
Fiberglassed the LR quarter, fitted the chrome trim and tail light assy.  It really needs the left end of the tail light panel replaced, but trimmed the tail light assy and fudged a little, looks ok.
Fitted the two headlight bezels.  Looking from above the top of the fender fit is a straight line, from the side the fender has a crown to it.   The body shop had the support tabs for the two top bezels screws too far forward and off to one side or WTF.  Welded in new tabs to support the bezel screws, this disbonded the bondo the body shop put on...OH well.   With the bezels fitting, finally had the grille and bezels on the car together.  Fit was not perfect, but very good.  To save a bunch of hassle I would next time buy the replacement 1970 front fenders that include the correct headlight backer structure, and correctly located bezel support tabs.  Decided to go black for the grille color.  Need to find the SEM paint.
Been working on the wiring.  Have the tail light wire harness checked out and installed.  Have the headlite wire harness rebuilt, had to clean and solder the brake proportioning valve wires as there was no connection due to corrosion.  Unwrapped and replaced the black electric tape for the entire harness.  Harness looks good and checks out 100% functioinal.  Am working on the engine compartment harness.  Removed the ICM and ballast resistor wiring. Also removed the red start interlock switch.  Will be eliminating the 1974 seat belt interlock, and replaced the auto trany neutral safety switch with the clutch pedal safety switch.   Adding wires for the HEI start, run, and tach.

Crank, rods, and pistons back from balancing.  The Ross forged pistons were lighter than the KB hyper, so was real easy to take a little more weight out of the crank throws.  The machining on the Eagle rods was close, but the small end bushings had a slight taper and the wrist pins fit tight.  The rod big ends were 2/10 thou under sized on all except one which was 8/10 thou under...thats almost 0.001 too small.  So had the rod big and small ends resized.   Sized the big ends to minimum spec for maximum bearing crush.   Probable would have been ok out of the box, but they are perfect now.  The machinist said they had not flipped the rods around when sizing the small end, that gave the taper to the bushing, and the big ends were cut all at once, they got hot during the sizing, and then shrunk when cold to a too small diameter.
Checked the piston to valve clearance.  With .525 valve lift  had 0.25 inch minimum clearance between piston and valve.
I had checked the lift on the Engle cam I bought months before they closed their doors.  All ok.   Decided to check the duration.  Seat to seat duration seemed wrong.
I'm going to have a good exhaust system, including headers so will go for single pattern cam.  Think I"ll go for solid lifter and follow the rule that we want the most valve lift for the least duration.   This is where alot of the older cam profiles fail.  They have reasonable lift, but long duration so street manners or low speed torque suffers.
Called one painter that I spoke with last fall, he said forget it.  So called another outfit, they said there is a slow spot now between snow storm wrecks, so took the car to them today.  Will be sanding down the solvent pops/fish eyes, and correcting other issues...reshoot the exterior of the whole car.  Hope all goes better this time.

i would rethink what cam your looking for and look into the comp thumpr series. or maybe a hughes cam. i personally like a comp cam and have one in most everything in the yard which is a good many mopars. even with headers it never hurts to help out the exhaust valve remember it is pushing alot out of that short port.

I here what your saying.  I'm staying with the Mopar specific lobes for .904 lifter diameter to get the faster cam lobe ramp speeds that the larger diameter lifter can handle.  I'm going with single pattern cam because along with the headers I'll be using David Vizard's exhaust system design as described in his book "How to Build Horsepower: Volume 1", ISBN-10: 0931472245.  In summary he says: the best engine performance is with open headers.  The length of the collector and its exit to open air helps tune the power band of the engine.
Collector length should be roughly between 16-24 inches where the longer length is for lower rpm torque.  So with a full exhaust system we want to duplicate that as close as possible.    The exhaust dumping into open air can be approximated by the pipe diameter and location of the crossover tube between left and right exhaust pipes, so thats where the "H' pipe or "X" pipe comes into play, because thats where a large change in volume occurs just like at the end of the open header collector. After the "H" or "X" , as long as the pipe diameter is sufficient for the engine power, and the mufflers are relatively free flowing, you will have minimal TQ and HP loss.  I don't pretend to be the expert, just trying to follow what he suggests.

If cams where available with maybe just 4 degrees extra exhaust duration I might have gave it a try, but most have 8 deg or more extra duration that to me seems more for cast iron systems.

On the duration problem with the Engle cam, I found my mistake.  If I read the seat duration at 0.006 lift as their spec says, then the seat to seat duration of the cam is correct.  I was reading duration at zero to zero lift, which obviously made a big difference.  So the cam is ok and on we go.

Car is back from repaint.  I had them fix a number of issues such as cracking welds, solvent pops, orange peal, paint runs, dirt in the clear coat, and very little clear coat left after they buffed the crap out of it trying to hide the "pops".
Car looks alot better.  They were able to cut nearly all the pops out, but would have had to start over blocking primer to completely eliminate them.  Paint finish looks 100% better.  Resprayed the whole car with Standox base and their premium clear coat.

Finished my home made oil pan baffle and windage scraper. After mig welding, I filled the pan with solvent and checked for leaks.  There were none.  So much better results than the last pan I welded on an oil pan with a oxy-acet torch.
Need to file fit piston ring end gaps, check pushrod guideplate alignment, and valve stem to guide clearance then will be putting the long block together.
Photos include the new paint, 5 quart oil pan with 4 quarts in it, and baffle/scraper.

Darin Morgan in his speedtalk presentation of "porting by the numbers" says the intake port short turn apex needs to have the smallest cross section for maximum port velocity.  He goes on to say airspeed is more important than anything else.  He said the port should taper from its entrance at the carb plenum (largest cross section) to the short turn apex with the smallest area for maximum port velocity just before the short turn bowl.
Made port mold of modified intake port.  Looks good.  I wanted to open up the pushrod pinch so the apex of the port short turn would have the smallest cross-section.
I cut the port molds at the following locations:
                        Intake    pushrod    short turn     mid turn      throat just below
                        gasket     pinch         apex          in bowl            valve seat
unmodified
cross-section       2.55       1.79          2.26           2.76                   2.60
area                                                                               (90% of valve O.D.)

ported area         2.55        2.14          2.30          2.76                   2.60

So at least the pushrod pinch area is close to the apex area, thus the velocites will be similar, as Darin said airspeed is most important.  He also said the throat being 90% of the valve diameter will show better flow numbers on the flow bench, but reducing the size to 88% will show increased torque and power on the race track.  He said the flow bench is only a static test, and the race track is the ultimate test.
The throat is supposed to be the smallest cross section area, followed by the pushrod pinch, with the bowl the largest area to help slow the velocity down to help flow turn the short turn without separating the fuel from the airstream.   If Edy had made the throat only 88% of valve OD then it would have been the smallest area.
Will any of this make much difference on a street/strip car.  For the way I drive probably not...but I love to tinker, and every little bit adds up.

Checked valve stem to guide clearance.  Mixed and matched the valves to the guides to get the most consistent clearances.  Ended up with 0.001 minimum on the intake valves, and 0.0015 on the exhaust valves.  This is exactly what the consensus was on the Speedtalk forum for bronze valve guides.  For a strictly race car probably want to open up the exhaust to closer to 0.002, but some of the speedtalk "guru's" said 0.002 was the upper limit and they would replace the guides at that point.  They said loose guides will ruin the valve seat job quickly, with a drop in engine performance.
I will be running positive valve stem seals on the intake valves and "old style" rubber umbrella on the exhaust to let a little more oil leak by for lube and valve stem cooling.  Umbrella seal part number Pioneer VS-232P, with half the umbrella cut off to let a little more oil onto the valve stem, similar to the OEM seals used on the older mopars.

Mocked up the valve train with checking springs to locate pushrod guide plates to align rocker arm roller tips with the valve stems.  Another concern was I did not want the pushrods rubbing against the thin-wall brass tubing.  Any leak there would suck oil mist into the intake port.  Usiing a round sanding roll, had to slightly elongate the rocker stud holes on a couple guide plates, and flip one plate over to get best roller tip alignment.  Overall looks real good.  Also checked the valve face to seat patterns, all looked real good.  The intake valves are light weight, meaning thin valve heads, so there was not any room to back-cut the valve with a 30 degree cut behind the 45 degree face.  This back cut is said to be worth performance, but there was not room to do it.  The light weight valves allow for use of a more aggressive cam and/or increased rocker arm ratio without needing stiffer valve springs.  So the basic idea of light valves is a good one.   Smokey Yunick said to reduce the weight on everything on the valve side of the rocker arm pivot.  He said weight on the lifter side of the pivot did not seem to make as much difference.

Overall I have been please with the Edelbrock cylinder heads.  Good enough for my use for street with some strip.  The crank, cam and timing chain are in.  With the valve train checked I can finally assemble the engine.
Fitted the piston ring end gaps.  Bought the Seal Power file-to-fit.  Set gaps at 0.017 top ring, with 0.019 second ring.  Oil ring gaps were close to 0.030 the way the came in the box.

First photo is port mold with upper mold the modified port, wider pushrod pinch and reduced the head bolt bump near the valve guide.  Second pic is rocker tip alignment.  Third pic is guide plate/pushrod clearance. Last pic is the mockup.

Finished assembling the engine.  Been making trips to the parts yard to get OEM bolts, brackets, etc.
I decided to paint the engine to look factory high performance, including using OEM valve covers.  Inside the valve covers, I ground off the spot welds on one side of the baffle so I could clean behind them...its good I did, lots of gunk hidden in there; also allowed the baffles to be set a little higher off the valve cover gasket surface so they would clear the rocker arm polylocks.
I hand oiled the rocker arm roller tips, and trunion needle bearings.  Could tell they liked being pre-oiled as they rotated much easier when I was finished.   Took the oil pump apart, then cleaned, and lighty greased the rotating parts.  The light coat of wheel bearing or assembly grease always helps produce a quick prime of the oil system.  For a drive to rotate the oil pump, used an old oil pump drive with the cam gear teeth ground off, works great.  When priming the oil system, made sure oil was reaching the rocker arms which it was.  I decided to try the Joe Gibbs engine breakin oil with high zinc content.  7 bucks a quart, but is probably one of the cheapest expenses so far on this resto.

Engine mounts are from carquest...they had made in India or China...what a choice.  The china mounts were not the correct width where they bolt to the K-frame, and the holes for the K-frame thru bolt was much to low.  The India mounts fit correctly after I chamfered the locating hole in the engine bracket so the mount dowel would fit correctly.  I'm going to add a torque strap to the drivers side mount, from one of the block ears to the cross bolt where the mount meets the K-frame.  Total cost about $3.
I looked at the poly mounts, they have a very positive blow-proof design for sure.   I have seen stiff mounts like that transmit a lot of noise and vibration to the car…no big deal for a racer, but I have had customer cars where engine/trany mounts were replaced with non-OEM parts that had very stiff rubber…the cars rattled and shook, the exhaust system would shake around making all sorts of noise….Not one customer liked it.   Would typically spend the extra bucks for OEM parts and the problems were gone.   Since my chally will be a true street driver I’ll stick with OEM style mounts for now, with a drivers side torque strap.

Next will be attach the bellhousing to the block, then using a magnetic dial indicator check for correct centering of the round hole in the housing vs the crankshaft center.  Service manual says 0.003 inch runout is max allowed.  More than that have to use offset dowels to locate bellhousing to block.  The belhousing it not the original for the engine, and I had the round trany input hole enlarged to fit the larger input shaft bearing of the transmission.  Checked the bellhousing, I'll need 0.021 offset dowels, going to get them from Robbmcperformance products.
Then will be ready to put engine/trany in car from below attached to the K-frame. Have to pull the K-frame back out, but no big deal.   I've never done it this way, so thought what the heck.  When I worked as a dealership mechanic we never did it this way, taking the K-frame and suspension out to pull/install an engine would take way too much time...must be a resto sort of thing so don't ding up the new paint.  This is the main reason I'll try it.

Bellhousing was off 0.023 from crankshaft center, so installed 0.021 offset dowels from RobbMcperformance.  They are aluminum with allen set screw to lock them in place.  The dowel holes in my OEM aluminum bellhousing were not deep enough for the length of the dowels, so filed the "joggle" transition on each dowel to shorten the extended length.  Worked real well.   Final bellhousing center was within 0.0035 inch.
Mated the bellhousing, clutch release fork and bearing to the transmission, then attached that group to the engine.  Easy to visually see misalignment or bell not parallel to block.  Works much better than attaching the bellhousing to the engine first, and trany last.  When I attach the clutch disc and pressure plate to the flywheel I never need a clutch disc alignment tool.  Just loosely tighten a couple of the pressure plate bolts, enough to hold the disc, but still allow the disc to move, then reach in each of the 3 arced openings on the sides of the pressure plate, feel the "step" between the clutch disc and pressure plate mating surface that presses on the disc.  Make this step the same at all 3 locations, then tighten the pressure plate bolts.  The trany will slip right into place.  This method has worked every time for 33 years and counting.
The hooker super comp headers went on with no issues, I added a little more clearance between one of the primary tubes and the mini starter, otherwise no problems at all.  Used Felpro exhaust manifold gaskets with slight trimming at the top of the center two ports to match the cylinder head ports.
Used an engine hoist to set the engine/trany onto a trany jack, with small square of plywood between the trany jack and oil pan, then had a snowmobile dolly under the aft end of the trany.  The dolly has a little square pad about 6-8 inches on a side, with 4 wheels, one at each corner.  A floor creeper would work under the trany too, but I wanted it free to use.
Jacked up the body, it lifted by hand, but I used the floor jack and jack stands to raise the nose of the car enough then rolled the complete unit under the car.  Lowered the car, then raised the trany jack until I could start the K-frame bolts, and attached the rear trany mount.  Put in the new 0.92 diameter torsion bars, and started attaching the front suspension pieces.   I had not removed the disc brake calipers, just wired them up out of the way, but they need to be sort of in location before reattaching the upper control arm/shock absorber lower bolt.
So in summary, when installing engine and trany as a unit, and front suspension is loosely installed or not there yet, putting everything in from below is an easy way to do it.  Need to either make dedicated support tools on wheels like I see many forum folks using, or gently balance the whole thing on a trany jack or such like I did, just don't shove on it any old place or you might slide the whole thing off the jack.  I had no problems, but only nudged it with my foot a little here a little there.
Clutch linkage torque shaft (zbar) that I have doesn't fit, it is for a big block, so ordered the correct one from Brewers Performance.   Taillight assy are in, rear bumper and bumperettes in.  Front turn lenses arrived, so they are in.
Rebuilt the thermoquad carb using a NAPA Echlin kit, everything went together well.  Had new bronze bushings installed for the primary throttle shaft, used K-liner thinwall valve guides for 3/8 diameter shaft. Correct/minimal clearance of the throttle shafts will help with smoother idle.   Cobbled parts from 3 different carbs including the brass floats from my original tquad carb off my old 340 duster.
Hurst shifter and linkage are in.  Linkage is nice and snug, added washers where needed.  Drilled a hole in the trany hump to allow a 1/4 diameter pin to be inserted thru the shifter so linkage can be set correctly.  Used a rubber plug to fill the hole after I was done.  The carpet will cover the plug.  I'll be the only one that knows its there.
Stripped the argent color off the grille, painted it SEM trim black, will install it and front bumper next.  Power steering pump can go in soon as pulley is painted.

Here are my calculations for the homemade engine torque strap:
Material is A36 hot rolled mild steel, with yield strength = 36,300 psi
Take off 10% of yield strength for production tolerance = 32,670 psi
For 2 times factor of safety  (thats 2X) = 32,670/2 = 16,335 psi
Material cross section at bolt hole: 1/8 x 1/2 = 0.0625 sq. inches
Yield strength:  16,335 lb/sq inch x 0.0625 sq inch = 1020 lb.
So torque strap can lift 1020 pounds and still have a factor of safety of 2, meaning the strap should be able to lift 1020 x 2 = 2040 pounds before deforming.
The 1020 pounds is plenty for my use.  Maybe if your pulling the front wheels off the ground you would want a thicker strap. 
Its not letting me post pictures.  Says uploader is full.
