Chevrolet Performance 90-Degree V6 Aluminum Engine Blocks

Chevrolet Performance 90° V6 Engine Blocks have been improved to handle the ever-increasing power levels of today's racing. Cast from A-356 aluminum and heat treated to T-6 specifications, these blocks weigh only 78 pounds yet provide 37,500 psi.

The new block design accommodates up to 4.125" cylinder bores and 4.000" stroke crankshafts, allowing the flexibility to build engines from 3.0L to 5.2L. New splayed 4-bolt main bearing caps are machined from 4340 chrome-moly steel with precision ground mating surfaces. An upgraded dry sump oiling system has three V8-style oil galleries above the cam tunnel for trouble-free lubrication at high RPM. The deck surface is .620" thick, and the front and rear bulkheads are reinforced. Flared head bolt boss holes have been blind-tapped to eliminate coolant leaks but can be drilled to full depth for turbocharged applications.
