Speedmaster Ford 351W Windsor 408/434 ci 4.030" Flat Top Forged Pistons PCE305.1090.03

Speedmaster's Ford 351W Windsor forged pistons are precision-engineered components designed for high-performance engine builds and rebuilds. Built with a flat-top crown design, these pistons feature a 4.030" bore diameter and are compatible with 408 and 434 cubic inch engine displacements, making them ideal for serious enthusiasts looking to upgrade or restore their classic Ford engine.

These forged pistons deliver the durability and strength needed for demanding engine applications. The flat-top design provides efficient combustion chamber geometry, while the forged construction resists deformation under high compression and boost conditions. With critical dimensions of 1.250" pin height and 0.927" pin diameter, these pistons integrate seamlessly into your Windsor engine assembly, whether you're building a street engine or a competition-grade power plant.
