Seller's Description
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 383 Bare Block (1986 – Later Style), 1-Piece Rear Main Seal • Cast-iron 4-bolt block • 4.004" bore • Torque plate honed • Clearanced for 3.800" stroker crankshaft • Machined for hydraulic roller or flat tappets Specs: • Part Number: 88962516 • Casting Number: • Deck Height: 9.025" • Lifter Pattern: Standard • Cylinder Wall: Open • Bore Range: 4.000" - 4.030" • Main Bolt: 4 • Main Bolt Degree: Straight • Cap Material: Gray Iron • Crank Journal Size: 350 • Oiling: Wet • Seal Type: 1 Piece • Max Stroke: 3.800" • Weight (lbs): 181 • Max HP: 450 • Usage: Street
