Mahle MS Piston Set BBC 466ci 4.310in Bore 4.00in Stroke 6.385in Rod .990 Pin 48cc 13.0 CR Set of 8

If you're building a high-performance Big Block Chevy engine, getting the right pistons is crucial for power and reliability. This Mahle MS Piston Set is designed for 466 cubic inch BBC applications, specifically for standard deck height blocks with a 9.800 inch deck. These pistons are forged from 2618 aluminum, a strong material commonly used in performance applications because it can handle high temperatures and pressures without deforming.

This set features a 4.310 inch bore and is designed to work with a 4.00 inch stroke crankshaft and a 6.385 inch connecting rod, creating a 467 cubic inch displacement. The dome volume is 48cc, which, combined with your cylinder head chamber volume, will determine your final compression ratio. For this specific setup, the compression ratio comes out to 13.0:1, which is suitable for race gas or high-octane pump gas in performance street applications. The included wrist pin is 0.990 inches in diameter, a common size for performance connecting rods. Each piston weighs in at 634 grams, which is a good balance for strength and rotational mass in a performance engine.

Keep in mind that these pistons are not CARB approved and cannot be shipped to California. They also carry a Prop 65 warning. This set includes eight pistons, enough for a complete V8 engine build. Ensure you have the correct cylinder heads and camshaft to complement this high-compression piston setup for optimal performance.
