PRODUCTION-BASED BLOCKS When building a mild Small-Block performance engine or a replacement for a stock engine, production-based blocks from Chevrolet Performance give you 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-later engines.
Production-Based Block Technical Notes: • Standard 350 main journal sizes • Non-siamese bores • Production-spec cylinder wall thickness • Lifter valleys machined for hydraulic-roller and flat-tappet valvetrains
