Product Details

This set includes eight Mahle MS Godzilla forged pistons, designed for 446 cubic inch Ford engines. Each piston features a 4.225-inch bore and a 3.976-inch stroke, with a 6.319-inch rod length and a 0.990-inch pin diameter. The pistons have a -7.8cc dish volume, contributing to a 12.0:1 compression ratio, and each weighs approximately 516 grams.

These pistons are constructed from 2618 aluminum, a strong material commonly used in high-performance applications. They come with a thermal barrier coating (TBC) on the crown, which helps to reflect heat away from the combustion chamber. This can lead to improved thermal efficiency and potentially reduce detonation. The piston skirts are also coated to reduce friction during operation.

This set is intended for builders looking to maximize performance from their Ford Godzilla engine. Please note that these pistons are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and assembly procedures.
