When you're building a serious performance engine, especially a stroker like this Big Block Pontiac 468ci, the pistons are a critical component. What you get in this Mahle MS Piston Set are the pistons themselves, along with the necessary rings and pins to get them installed. These are flat-top pistons designed for a 4.185-inch bore and a 4.250-inch stroke, with a 6.800-inch rod length and a 0.990-inch pin diameter. The compression height is 1.285 inches, and the dish volume is -6.4cc, which Mahle calculates will result in an 11.0:1 compression ratio with the specified stroke and rod length.

Mahle is a well-known name in engine components, and these pistons are made from 4032 aluminum alloy. This material is chosen for its strength and durability, especially under the high temperatures and pressures found in performance applications. The pistons weigh in at about 542 grams each, which is a reasonable weight for this type of forged piston. They are designed as a direct fit for Big Block Pontiac 468 cubic inch engines, making them a solid option for rebuilding or upgrading your engine's internals. Keep in mind that these pistons are not CARB approved and cannot be shipped to California.
