302-01381 PONTIAC Cylinder Block Supercharged Option Regal

Review PONTIAC Cylinder Block Without Supercharged Option Fits for REGAL 1990–1992

The Pontiac 302-01381 cylinder block is a high-performance component designed specifically for supercharged applications of the Pontiac Regal from the model years 1990 to 1992. This cylinder block is distinguished by its robust design and enhanced durability, which enables it to withstand the increased pressures and temperatures generated by the supercharger system.

The 302-01381 cylinder block is manufactured using advanced casting techniques to ensure a uniform wall thickness and exceptional strength. The block features a 5.7-liter, V8 configuration, with a bore and stroke measurement of 4.00 inches (101.6mm) by 3.48 inches (88.4mm), respectively. The cylinder bores have a finished surface that is honed to ensure a precise fit for the pistons, while the crankshaft journal surfaces are machined to provide a precise fit for the crankshaft.

The 302-01381 cylinder block also features a unique design for the supercharger interface. The block includes a raised area on the intake manifold surface to accommodate the supercharger's drive pulley. This design allows for a secure and efficient connection between the supercharger and the engine, ensuring optimal air induction and power output.

Additionally, this cylinder block has been heat-treated to improve its strength and durability. The process involves heating the metal to a specific temperature and then cooling it slowly to create a stronger microstructure. This treatment makes the block less susceptible to fatigue and failure, even under the high-stress conditions of a supercharged engine.

The 302-01381 cylinder block is designed to work seamlessly with the other components of the supercharged Regal engine. Its precise measurements and finishes ensure a proper fit and function, while its enhanced durability and strength make it well-suited for the demands of high-performance driving. This cylinder block is an essential upgrade for any enthusiast seeking to maximize the power and performance of their Pontiac Regal.
