Mahle MS Piston Set SBF 347ci 4.032in Bore 3.4in Stroke 5.4in Rod .927 Pin -6cc 10.1 CR Set of 8

Mahle's MS Piston Set is built for Small Block Ford engines, specifically those configured for sealed race applications like the popular 347 cubic inch displacement. These pistons feature a 4.032-inch bore and are designed to work with a 3.4-inch stroke and a 5.4-inch connecting rod, utilizing a .927-inch pin. The -6.5cc valve reliefs are engineered to achieve a 10.0:1 compression ratio with the specified components, making them a solid choice for builders aiming for a specific performance target.

Crafted from 4032 aluminum alloy, these pistons offer a good balance of strength and lighter weight compared to cast iron, which is crucial for high-RPM engine operation. Each piston weighs in at 403 grams, contributing to overall engine balance and reducing reciprocating mass. This set includes eight pistons, providing everything needed for a complete engine rebuild on a V8 Small Block Ford.

It's important to note that this piston set is not CARB approved and cannot be shipped to California. Always consult your engine builder or Mahle's technical documentation for precise assembly details and compatibility with other engine components to ensure optimal performance and longevity.
