Post your 383 combos with a 440 crank. I plan on using my 383 block with steath heads. I am considering using a 440 crank? Looking to give it some bottom end but dont want to sacrifice the car hooking every pass. Wondering what to expect for ET in my 3800lbs 4 door Belvedere. Undecided to use a flat tappet or roller cam. Any suggestions will be appreciated.
