Mahle MS Piston Set Chevy 430ci 4.135in Bore 4.000in Stk 6.000in Rod .927 Pin 6.0cc 14.2 CR Set of 8

If you're building a high-performance Chevy 430 cubic inch engine, this Mahle MS Piston Set is a solid choice for your top end. Mahle is a well-known name in engine components, and these pistons are built for serious work. They are designed to handle the demands of a performance build, offering a specific compression ratio and bore size that's crucial for tuning your engine's power output.

This set includes eight forged pistons, each weighing in at 426 grams. The material, 2618 aluminum, is a popular choice for performance pistons because it offers good strength and thermal expansion properties, which are important for reliability under high heat and pressure. The pistons feature a 4.135-inch bore and are designed to work with a 4.000-inch stroke crankshaft and a 6.000-inch connecting rod, with a .927-inch pin diameter. The 6.0cc dish volume combined with the bore and stroke results in a 14.2:1 compression ratio, which is on the higher side and typically suited for race gas or E85 applications where detonation control is managed. It's important to note that these pistons are not CARB approved and cannot be shipped to California. They also carry a Prop 65 warning.

When installing these pistons, ensure you're following the manufacturer's recommended clearances and lubrication procedures, especially given the high compression ratio. Proper ring gap setting and cylinder wall preparation are critical for performance and longevity. This set is a key component for anyone looking to maximize the power and efficiency of their Chevy 430ci engine build.
