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."

Lyn, not sure where the budget is, but a sleeved pre '68 327 would be a great way to go. A savvy machine shop will have access to sleeves that are reasonably priced.

Neat project and car.
