Competition Which block?

[DieselBoy109]

Can someone clarify which blocks are good and which ones are bad? I know the Brazil number 53 is bad but which ones are good and which one does my truck have? 96 dodge

Yes stay away from the 53's. Im thinking most are the same as far as casting. The older blocks I think 94 or 95 and older have the 14mm main studs. They only have 1 turbo drain cast into the block.
