Mahle MS Piston Set SBF 347ci 4.030in Bore 3.4in Stroke 5.4in Rod .927 Pin -6.2cc 10.4 CR Set of 8

If you're building a high-performance Small Block Ford engine, especially one based on the 347 cubic inch displacement, a solid set of pistons is crucial. This Mahle MS Piston Set is designed for that purpose, offering a well-built foundation for your engine's power output. These pistons are specifically made to work with Twisted Wedge 11R cylinder heads, ensuring proper geometry and compression for that setup.

This set features a 4.030-inch bore and is designed around a 3.400-inch stroke with a 5.400-inch rod, contributing to the 347 cubic inch displacement. The pistons have a -6.2cc dish volume, which, combined with the other engine components, results in a 10.4:1 compression ratio. This compression level is a popular choice for naturally aspirated performance builds, offering a good balance of power and pump gas compatibility. Each piston weighs 437 grams, and they utilize a standard 0.927-inch pin diameter, making them compatible with many common connecting rods.

Mahle is known for its engine components, and this set is no exception, built from 2618 aluminum for strength and durability under demanding conditions. It's important to note that these pistons are not CARB approved and cannot be shipped to California. Ensure you have the correct cylinder heads and connecting rods for this piston set to achieve the intended performance and fitment.
