383 is a 400 crank in a 350 block. Heck a 283 with some small aluminum heads would be perfect.

383 is a 400 crank in a 350 block. Heck a 283 with some small aluminum heads would be perfect. I had a 283 with iron heads. It was heavy and made a reliable 250hp. good heads and a bigger cam could make an easy 300hp. the very small bore of the 283 presents valve shrouding challenges, finding a set of aftermarket "vortec" heads with small chambers to keep up the compression or milling the heads would solve this. |
