Forged from 4032 alloy aluminum right here in Mentor, Ohio, these Wiseco Pro Tru Street pistons are built for your Chevy 400 engine. They feature a flat top dome with a -7cc dish, designed to work with a 4.155-inch bore and accommodate a 3.480-inch or 3.750-inch stroke with a 1.560-inch compression height. This set is designed for street use, aiming for a balance of performance and quieter operation compared to more aggressive racing pistons.

What really sets these apart is the ArmorGlide skirt coating.
