Mahle MS Piston Set SBC 414ci 4.125in Bore 3.875in Stroke 6.0in Rod .927 Pin -5cc 11.9 CR Set of 8

If you're building a high-performance Chevrolet Small Block engine aiming for around 414 cubic inches, this Mahle MS Piston Set is a solid foundation. These pistons are designed to work with a 4.125-inch bore, a 3.875-inch stroke, and a 6.0-inch connecting rod, featuring a .927-inch pin diameter. They are specifically crafted for applications where a 11.9:1 compression ratio is desired, with a -5cc dish volume.

Mahle uses 4032 aluminum alloy for these pistons, which is a well-known choice for performance builds because it offers a good balance of strength and thermal expansion properties. This material helps ensure the pistons can handle the stresses of a performance engine while maintaining proper clearance as temperatures rise. Each piston weighs in at 418 grams, contributing to a balanced rotating assembly. This set includes all eight pistons needed for a V8 engine.

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 to achieve the best results from your build.
