Re: Attn. 265 Racers.What block is the best?
Here is what Mr.Bill Jenkins said about 265 blocks in his 1971 Chevy Power Guide."In the case of the 3-3/4 inch bore blocks,the best one to use is the original 1957 castings.These 57 blocks featured a heavier top deck or head surface for better strength and optimum gasket sealing. They also had the constant feed lifter gallery oiling,which is more desiable."
