Mahle MS Piston Set BBC 466ci 4.310in Bore 4.00in Stroke 6.385in Rod .990 Pin 28cc 10.6 CR Set of 8

This Mahle MS Piston Set is built for Big Block Chevy 466 cubic inch engines. You get a complete set of eight pistons, designed to work with a 4.310-inch bore and a 4.00-inch stroke. These pistons are intended for standard deck height blocks, meaning the distance from the crankshaft centerline to the deck surface is 9.800 inches. This set is a solid option if you're building or rebuilding a performance Big Block Chevy and need reliable, well-built internal components.

Each piston in this set features a 28cc dome volume, which contributes to a 10.6:1 compression ratio when paired with a 4.00-inch stroke and a 6.385-inch connecting rod. The pistons are forged from 2618 aluminum, a strong material commonly used in high-performance applications because of its durability and ability to withstand high temperatures and pressures. They come with a 0.990-inch pin diameter, a standard size for many performance Big Block Chevy builds. Each piston weighs approximately 599 grams, which is a notable weight for a forged piston of this size, indicating a robust construction.

It's important to note that these pistons are not CARB approved and cannot be shipped to California. Additionally, they carry a Prop 65 warning. For installation, ensure you consult the manufacturer's detailed instructions, as proper ring gap, piston-to-wall clearance, and assembly procedures are critical for engine longevity and performance.
