I built this for a customer over 6 years ago, basic forged 331 AFR 185, small blower can, gt40 intake and 12psi of intercooled STRIM boost.

Cracked lifter valley, #2,3 and 4 main, broke can in half. Funny thing is the rotating assembly, bearings, lifters and all parts look great. Only symptoms we had were 4 dead cylinders, hell it even sounded normal while running.

Wildest thing I've ever encountered thought I'd share...

The new Dart block with some other goodies will be just fine

They make new pistons every day, so why worry?

Broken cam sure is neat. I had one a few years ago the cracked the block: mains, cam journals and lifter valley had 2 cam bearings fall out and the only clue we had was 8 psi of oil pressure, he'll we drove it 30 minutes home from the track like that. All in all no one can say that these things aren't incredible.

Yeah it was carrying 35psi at idle and 50psi when I blipped the throttle. 2nd cam bearing was out, 3rd and 4th were slid out and beat up.

I'd say he got his money's worth out of that block. 500hp on a stock block for 6 years..lol. Damn, you build some good stuff there Sir.

That right there is why I don't think I'd ever bother to put nice parts in a stock roller 302 block! Hell I'm building a 351 and I'm still probably going to run the stock crank at a minimum haha.

Wow ....Fortunate he didn't end up with a pile of scrap metal. So that rotating assembly can be reused?
