Wiseco Ford Small Block 302 4.030in Bore 1.280in CH -20.00 CC Piston Set

Wiseco is well-known for making strong, reliable internal engine components, especially for performance applications. This Professional Series piston set is a prime example, built specifically for Ford Small Block 302 engines with a 4.030-inch bore. These aren't your average pistons; they're designed for builders who push their engines hard, whether that's on the track or in a severe-duty street application.

Each piston in this set is forged and machined in the USA from 2618 aluminum, a material chosen for its improved tensile strength under high stress. You'll find precision ring grooves, anti-detonation grooves, and other features aimed at improving ring seal, which is critical for power and engine longevity. They also come with an ArmorGlide skirt coating that helps reduce friction and resist seizure, while also contributing to quieter operation. The fully machined crown and forced pin oiling further demonstrate the attention to detail in these pistons, all aimed at handling the demands of heavy to severe duty performance builds.

This set includes eight pistons, each with a 1.280-inch compression height and a -20.00cc dish volume, designed to work with a 0.927-inch pin diameter. Please note that these pistons are not CARB approved and cannot be shipped to California. If you're building a high-performance Ford 302 and need internals that can handle serious abuse, this Wiseco set is a solid option.
