I also thought 327 or even a 283. It sucks people will try to rip others off like that. A rod knock, huh? You know good and damn well when you turn your oil pan into a jewelry box! Sorry about your misfortunes, maybe between that carb, intake and those heads you can make your money back. I wouldn't try to do anything with that block though it looks busted in the pics and I'm sure there's issues you can't see. Good luck.
