Re: Cracked 350 Crank, build 383?
I might agree with the L31 advice, or if you have time yank it out and have a shop check it out. I went with a 4-bolt main 350 195-249hp crate motor (hp rating varies depending on the web site) but am adding a Comp Cams roller cam & lifter set with Brodix IK-180 alumimum heads. Had I took more time to investigate, I may have gone with a Vortec L31 and maybe a different cam. Or had the timing worked out, my cousin just gave my dad a later 350 with a 1-piece rear seal and provisions for a factory roller cam ('95-'99, casting 10243880), which would be a great block to build on.
