they are all the same strength 500-600hp max, yes even the "mexican" if you wanna try to push the stock block, get a stud girdle and try cryogenically treating the block, when i break mine i may do a "cryo" block

I would install some of the valley reinforcement cross-straps instead
or a stud gridle.

Block is weak in the valley, not on the bottom end.

all a girdle and valley reinforcements are going to do is hold your block together after it cracks!!!!
