Id say a lil more then that..... On a side not that can be done with a stock crank no problem.... if your gunna spend the $$$ on a forged crank ya might as well go with a 383 and let the ci help ya also.

I agree, go with a 4.00 stroke on the crankshaft if you are putting a forged crank into your block. You'll be making more rwhp than 650 at 15 psi with your combination. Bob
