Disassembly of a 69 Z/28 DZ Three Oh Blew Engine

[SuperNovaSS]

Thanks for the replies guys. I didn't see any stampings on the cam. I believe it was a stock replacement. I believe a threadsert in the cracked threads along with the sleeves should fix the problem you are pointing out. I have had blocks that were good runners for a long time with that type of repair. It is lifter valley, cam journal, and main area cracks that I could not see that would make this block junk. I agree this block would be a boat anchor already if it was most any other application. Can you imagine how many other DZ blocks with less damage were tossed out since it was just a 4 inch bore 4 bolt block?
