Mahle MS Piston Set SBF 331ci 4.030in Bore 3.25in Stroke 5.4in Rod .927 Pin -6cc 10.0 CR Set of 8

Mahle's MS Piston Set is built for Small Block Ford engines, specifically those with the Twisted Wedge cylinder head. These pistons are forged from 4032 aluminum, a well-known material for its strength and thermal expansion properties, making them a solid choice for performance builds. The set is designed for a 331 cubic inch displacement, featuring a 4.030-inch bore and a 3.250-inch stroke, paired with a 5.400-inch connecting rod and a .927-inch pin.

Each piston in this set has a -6.2cc dish volume, which, when combined with the Twisted Wedge heads, helps achieve a 10.0:1 compression ratio. This compression level is a popular target for many performance street and strip applications, offering a good balance of power and drivability. The pistons weigh in at 438 grams each, contributing to a well-balanced rotating assembly. This set includes eight pistons, ready for your next engine rebuild.

Please note that this piston set is not CARB approved and cannot be shipped to California. It is also subject to California's Proposition 65 warning.
