When building a mild Small-Block performance engine, production-based blocks from Chevrolet Performance offer strength, accuracy and peace of mind that can’t be assured in a rebuilt core. And, unlike so many of the used cores, nearly all of ours feature four-bolt main caps for extra strength. Each cylinder block is machined to production-spec tolerances and is manufactured to the exact specifications of pre-1986 or 1986-and-later engines.
