Mahle MS Piston Set SBC 427ci 4.125in Bore 4.000in Stroke 6.0in Rod .927 Pin -20cc 10.4 CR Set of 8

If you're building a high-performance Chevrolet Small Block engine, this Mahle MS Piston Set is a solid choice for your 427 cubic inch application. These pistons are designed for a 4.125 inch bore and feature a 4.000 inch stroke with a 6.0 inch connecting rod. The -20cc dish volume contributes to a 10.4:1 compression ratio, making them suitable for many street and strip builds where pump gas is still a consideration.

Mahle is known for well-built engine components, and this set is no exception. Constructed from 4032 aluminum alloy, these pistons offer good strength and durability while remaining relatively lightweight. The 0.927 inch pin diameter is standard for many performance applications. Each piston weighs in at approximately 422 grams, which helps with overall engine balance. This set includes all eight pistons needed for a complete V8 engine build.

Keep in mind that these pistons are not CARB approved and cannot be shipped to California. Always refer to your engine builder's specifications and the manufacturer's installation instructions for proper assembly and tuning.
