They are much stronger in the cylinder walls and deck. The bores will stay round and straight. The lifter bores are also very accurate on the aftermarket blocks. Believe me it will be money well spent. I wont even fool around with stock blocks any more and its real hard to find the older 4 bolt main blocks that are the best.

Very good advice Mike....there is no saving $$ in drag racing ...purchase a bow tie block, it will last you forever.....do it right the first time, you will be glad you did.....
