Mahle MS Piston Set Ford 434ci 4.09in Bore 4.125in Stroke 6.7in Rod 0.990 Pin -7cc 11 CR Set of 8

If you're building a Ford FE engine to displace 434 cubic inches, this Mahle MS Piston Set is a solid choice. These pistons are designed for a 4.090-inch bore and work with a 4.125-inch stroke crankshaft and a 6.700-inch connecting rod. The 0.990-inch pin diameter is standard for many performance applications, and the -7.5cc dish volume, combined with the other engine dimensions, results in an 11.1:1 compression ratio. Each piston weighs in at approximately 487 grams, which is a well-balanced weight for performance and durability.

Mahle uses 4032 aluminum alloy for these pistons, a material known for its strength and resistance to thermal expansion, making it suitable for high-performance street or strip applications. This alloy helps ensure the pistons can withstand the demands of a performance engine build. The set includes eight pistons, all manufactured to Mahle's exacting standards to ensure they fit right and perform reliably. This is a critical component for anyone looking to rebuild or significantly upgrade their Ford FE engine.

Keep in mind 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 tuning to achieve the best results from your new Mahle pistons.
