Mahle MS Piston Set SBF 347ci 4.125in Bore 3.25in Stroke 5.4in Rod .927 Pin -6cc 10.0 CR Set of 8

If you're rebuilding the heart of your Ford Small Block engine for a 347 cubic inch displacement, a solid set of pistons is crucial. This Mahle MS Piston Set is built for that purpose, designed to handle the demands of a performance-oriented engine build. These pistons are specifically sized for a 4.125-inch bore and utilize a 3.250-inch stroke with a 5.400-inch connecting rod, ensuring proper geometry and fitment within the engine block.

Constructed from 4032 aluminum, these pistons offer a good balance of strength and lighter weight, which helps reduce reciprocating mass. The -6.5cc dish volume, combined with other engine components, helps achieve a 10.0 compression ratio, a popular target for many naturally aspirated and forced induction builds. Each piston weighs in at 415 grams, and they come equipped with a .927-inch pin. This set includes eight pistons, ready to be installed in your 347ci Ford Small Block.

It's important to note 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 break-in procedures to ensure the longevity and performance of your new engine.
