400-450hp 355 on a budget?

[Pete357]

Block is in at the machine shop! Im letting him decide on the heads, what ever he thinks i need, this guy has been at building engines for a while so i trust his expertise. He seems to think i will be totally in the clear at 500hp...if that happens, with my 2 bolt main. I just hope all the stars align because with our conversation on the phone today he thinks i should easily have a 450-500hp combo. Im pretty excited to get my block back from machining along with the box of parts to get her together. Once i have it togather its going back to the same shop im getting the machining done at for some runs on the superflow dyno. Ill keep yall updated with progress as i here from the man.
