My 440 recipe

[73restomod]

I will send the heads and intake out to have them flowed together. Then I will see what and where any restrictions are thank you for the advise. That leaves the camshaft. I' m leaning towards a low advertised duration and 230s in/ex at .05, with lift that won't break the hydraulic roller lifters, any recommendations?

Not that there are not some smart people on this site, but when selecting a cam, call the major
cam manufacturers, and talk to their tech people, describing the details of your engine build,
and drive train, to get an additional opinion.  Saved me once, in that I was gonna install a cam that had too much
duration for my compression ratio. They'll also tell ya what kinda lifters to use, etc.

  You can get a custom grind from Cam Motion.

Lunati also has a number of Mopar only cam lobes available & can be custom matched to your needs

Yeah, I figured you needed some low speed performance - but I think the long rod will be sluggish with that head package. The high rod ratio lends itself to long low rpm service life. Because the stroke isn;t being drastically increased adding a larger volume port will cause the torque to be moved up in the rpm band - regardless of the intake design. A shorter rod moves faster and sooner than a long rod and that will help bring down the rpm range and flatten the torque curve. If  you're still in the design phase it might be fun to play with those on a simulator program and see how the power is affected.
On the camshaft - you don;t damage the lifter by having "too much lift". What you give up is ramp speed - that is the rate the intake valve opens. Any hydraulic gives up ramp speed because of the cushioning affect of the hydraulics. If torque is what you need then a flat tappet would make more of it, and lower, than a similar sized hydraulic roller. Also - the heads will be ported to flow at higher lifts - if you go too small you won;t be doing yourself any favors because hte port will never get fully used. So you want as much lift as you can get for a smaller duration. I think if you want to stick with what you have planned then something like the Comp XR280HR-10 would be a good choice. If you really want to get serious - once you've got your flow numbers - give Bullet a call and get a custom unit.

The big advantage is that the rod is only 30-40 grams heavy than an aftermarket lightweight rod, it's still lighter than the factory rod, and the piston is lighter than a comparable stock stroke/rod 4032 piston by over 100grams. Price is also lower because you can use off the shelf BB Chevy parts. At one point in time, before they had mopar stroker kits, this build was pretty common. The rod ratio from stock only went up by .01, so I'm inclined to believe that the low speed port velocity will be the same if not a little better than stock due to the 30 extra cubes.

Heck why not go for it and get the XR286 cam!!!

vrooommmmmmmmm!!!

I have the Lunati 60312 Hyd Roller Cam on my 505CI 440 (they changed the part # but you can still find it easily), with Edelbrock RPM Intake and Heads .  You will LOVE that cam based on your description of what you want to do, and the size you mentioned.... 

Also, my FACTORY 'six pack' coil mounting bracket location is right there on the Pass. side of the intake manifold by the fuel lines.  It is out of the way, and looks and works awesome there.  Apparently Chrysler was not worried about fuel leaks dripping on to it or anything 

Good luck!!!!!!!!!

Ya, the hot intake manifold and heads should ignite the gas anyway!!
