If you're building a high-performance Pontiac Big Block engine, this Mahle forged piston set is designed for stroker applications, specifically for a 488 cubic inch displacement. These pistons feature a 4.155-inch bore and are engineered to work with a 4.500-inch stroke and a 6.800-inch connecting rod, making them ideal for increasing displacement and power.

Constructed from 4032 aluminum alloy, these pistons are well-built for demanding conditions. They have a flat-top design with a -6.4cc volume, which contributes to an 11.5:1 compression ratio when paired with the right cylinder heads and gasket combination. The 0.990-inch pin diameter ensures a strong connection to your connecting rods. Each piston weighs approximately 506 grams, contributing to a balanced rotating assembly.

This set is intended for serious engine builds where reliability and performance are paramount. Please note that these pistons are not CARB approved and cannot be shipped to California. Always refer to manufacturer specifications for complete build details and compatibility.
