I'm putting together a 383 for the challenger. It's stuff I have around, so it's not an exotic build. The basics are 162 Keith Blacks .030, 915's with 174 hardened exhausts, mopar single plane, headman elites. For carbs, it's either a #4428 AVS, edelbrock1407, or maybe a 750 double pumper, of which I'm skeptical how streetable it would be. I've got a set of Crane steel malleable adjustable rockers I thought about finally using, even if I use a hydraulic cam. It will have a 4 speed behind it. Cam shafts are another thing. It's a confusing world, but I want streetable power with some vacuum. Don't mean to open a can of worms, but any suggestions? I'm asked why a 383 over a 440, but back when, I remember many 383's get the crap beat out of them and still haul the mail. I have no doubts it should have plenty of go for my ride. Besides, I assembles a 440 for the cuda a few years ago. I'd like to hear what cams worked good for people. Thanx.
