So... I've been really happy with my 383 in my PP, but i just picked up a fresh 406 short block that i couldn't pass up for the price. Has all eagle lower with flattop pistons. My uncle has some aluminum edelbrock e-tec 200cc / 64cc heads that he inst using that I'm able to steal from him...

What cam would you suggest for this build? Im either going to put this in my PP 185 or my dads 19 ft checkmate that we use up north... both equipped with alpha's SS drives.

I'm not an expert, but those chambers on flat top pistons in a 406 may need the intake valve to close way late to deal with the high c/r and stay pump gas friendly.

I can swap out those pistons with some 18cc-20cc to keep the compression around 9.5...

What are you running in the 383 ?
