Mahle MS Chevrolet Big Block 632cid 4.600 x 1.120RCH 10.0cc 570g 11.9CR Pistons (Set of 8)

Mahle is well-known for making high-performance engine components, and this set of MS pistons for Chevrolet Big Block engines is a prime example. These pistons are built for the demanding requirements of a 632 cubic inch displacement, designed to handle significant power and stress. They feature a 4.600-inch bore and are engineered to work with a 4.750-inch stroke, 6.700-inch rod, and a 0.990-inch pin. The 10.0cc dome volume contributes to an 11.9:1 compression ratio, which is ideal for maximizing power output in performance applications.

Crafted from 2618 aluminum, these pistons are chosen for their strength and ability to withstand high temperatures and pressures common in performance Big Block builds. Each piston weighs 570 grams, a carefully considered weight that balances strength with rotational mass. The 1.120-inch compression height is critical for proper piston-to-valve clearance and deck height, ensuring correct engine geometry. This set includes eight pistons, providing a complete solution for rebuilding or upgrading your Chevrolet Big Block engine.

Please note that these pistons are not CARB approved and cannot be shipped to California. They are also subject to California's Prop 65 warning. If you're building a high-performance Big Block Chevy, this Mahle piston set offers a well-built foundation for serious power.
