I own a '71 Challenger. It was originally a 318 car and had a junkyard 360 with some kinda small cam and a Weiand Stealth Intake with a 600 ED carb when I bought it. It was way too shortwinded for me so I sold that motor and put together a 416 from a .030" over 340 block I had in stock with a Ohio Crankshaft prepped 4" stroke crank, KB .070" 360 pistons and Eagle rods. I decided to use new heads for the 1st time on a street car and decided to go with the factory big port Commandos which I extensively ported with the help of my flow bench. They have cut-down 2.08" MP SS Intakes (to 2.04") and the 1.6" SS exhausts, CC Titanium retainers & locks and MP springs compatible with the .528" MP solid cam I used. After doing some trial fitting I found I could adapt some leftover B-1 big block roller rockers I had from another motor so I used them after moving the mounting block centerlines 1/8". They have a 1.7 ratio in this application so I have about .598" lift. I also used Crane 3/8" pushrods. I hope to go to a solid roller later on. It has a ported Victor Intake, 750 Demon vac carb, Xtreme airfilter, Digital 6 plus ignition with MSD wires and coil, Hooker super comp headers that I hacked the flanges off and welded Schoenfeld W-2 Head flanges on (the original flanges didn't line up with the ports
at all!) It has Poly engine and trans mounts and a Stef's aluminum pan & pickup and a complete TTI 2 1/2" exhaust and some new stainless mufflers I had laying around. It made 540hp and 510tq on the engine dyno with a Dominator, and 526/499 with the Demon carb it has now @ 6,250.
For the trans I found a great deal in the local Tradin' Times paper on a like new Dynamic prepped 904 with the 2.74 low gear and just switched the VB for a Turbo Action manual to avoid the kickdown link hassle, and put a deep pan and cooler on. It also came with a matching Dynamic 9 1/2" convertor made for a stroker motor. The rear is still the 3:55 posi 8 3/4 that came with the car and so far I just added a pinion snubber to hopefully keep the driveshaft in the car until I can get the chassis squared away. I also installed the Wilwood front disc kit and switched the stock master cylinder for a rebuilt disc brake unit because I
do not trust drum brakes on the road today.
Other mods I've did were to put a new fuel system in with a new repo tank, a 1/2" sending unit with a new 1/2" fuel line and a Holley blue pump & regulator. I also added EL power front windows with some adapted 90's Chevy cop car switches, a Jensen CD/Stereo and Bose speakers, all new seat covers from the local Interior shop, and the Centerline satin finish rims 15 x 5 & 15 x 9 with 275 Kelly tires on the back that do little for traction.
My DD beater is a '92 Iroc Daytona with a 3L V-6. It's not fast, but it gets great mileage, never leaves me stranded and stops and handles great.
