Mahle MS Piston Set BBC 496ci 4.310in Bore 4.25in Stroke 6.385in Rod .990 Pin 48cc 13.7 CR Set of 8

If you're building or rebuilding a Big Block Chevy 496 cubic inch engine, this Mahle MS Piston Set is a solid choice for serious performance. Mahle is a well-known name in engine components, and this set is built for demanding applications where strength and reliability are key. These pistons are designed to work with a standard deck height of 9.800 inches and feature a 4.310-inch bore, a 4.250-inch stroke, and a 6.385-inch connecting rod length. The 0.990-inch pin diameter is standard for many performance applications.

What sets these pistons apart is their construction and design for high compression. They have a 48cc combustion chamber volume, which, combined with the other engine dimensions, results in a 13.8:1 compression ratio. This high compression is ideal for naturally aspirated engines looking to maximize power output. The pistons themselves are forged from 2618 aluminum, a material known for its strength and ability to withstand high temperatures and pressures, making them well-suited for performance builds. Each piston weighs in at 606 grams, which is a reasonable weight for a forged piston of this size and application.

It's important to note that this piston set is not CARB approved and cannot be shipped to California due to emissions regulations. Additionally, it is subject to California's Proposition 65 warning. When installing these, ensure you follow the manufacturer's recommended clearances and assembly procedures for optimal performance and longevity. This set includes pistons for a V8 engine, meaning you get a complete set of eight.
