383 Bare Block
1986-Later Style
88962516 Chevrolet Cylinder Block
When building a mild Small-Block performance engine or a replacement for a stock engine, brand-new, production-based blocks from Chevrolet Performance give you strength, accuracy and peace of mind that can’t be assured in a rebuilt core. In addition, unlike so many of the used cores, this GM block features 4-bolt main caps for extra strength ﾖ there’s no reason to settle for a 2-bolt block. Each new cylinder block is machined to production-spec tolerances and is manufactured to the exact specifications for 1986 and later engines with one-piece rear main seal.
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
