Wiseco Chevy 400 ProTru Street 4.165 Bore FT 1.560 CH -7cc

If you're rebuilding a Chevrolet 400 small block engine, this Wiseco Pro Tru Street piston set is a solid option for getting your build back on the road or down the track. These pistons are forged from 4032 alloy aluminum, a material chosen for its strength and ability to handle the demands of street driving and occasional track use. They're made in the USA, specifically in Mentor, Ohio, which is a notable detail for those who appreciate domestic manufacturing.

This set comes complete with everything you need for an all-inclusive rebuild: the pistons themselves, high-quality chromium alloy steel piston pins, spiro locks for secure pin retention, and a set of piston rings. The pistons feature an AS-Forged dome with specific crown features designed for efficient combustion and oil drain-backs, helping to keep things running smoothly. They also include an ArmorGlide skirt coating, which is designed to reduce friction, resist seizure, and contribute to quieter operation compared to uncoated pistons. The -7cc dish in the piston dome helps achieve a specific compression ratio when paired with your cylinder heads.

It's important to 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.
