Wiseco BBC inchQ16inch Heavy NOS +42cc 1.120inch CH Piston Shelf Stock

If you're building a high-performance Chevrolet Big Block engine that needs to handle serious nitrous oxide, these Wiseco pistons are a solid choice. They're forged from 2618 aluminum, which is known for its strength, and then machined right here in the USA. This means they're built to handle the kind of stress that comes with heavy-duty racing applications.

Wiseco has packed these pistons with features to help them perform and last. You'll find precision ring grooves, an anti-detonation groove, and other features designed to improve ring seal. They also come with an ArmorGlide skirt coating that helps reduce friction and noise, while also resisting seizure. The crown is fully machined, and the piston features forced pin oiling to keep things well-lubricated under load. These are designed for engines with a 4.600-inch bore and a 1.120-inch compression height, with a 42cc dish to help achieve your desired compression ratio.

These pistons are designed to fit a wide range of Chevrolet Big Block applications, including many trucks and cars from the 1970s through the early 2000s. Remember that these are performance parts and are not CARB approved, so they cannot be shipped to California.
