Wiseco Chevrolet Small Block -5.7cc Flat Top 1.000 X 4.040 - Set of 8

If you're building a performance Chevrolet Small Block engine, especially for racing applications like drag or circle track, you need pistons that can handle the stress. Wiseco's RED Series forged pistons are designed specifically for these demanding scenarios. They're made from 2618 aluminum, a material chosen for its high tensile strength, which is crucial when you're pushing an engine hard or adding power adders.

Wiseco machines these pistons in the USA, using dedicated forgings that allow for an optimized, engine-specific strutted design. This approach maximizes strength while keeping weight down. You'll also find horizontal slot oiling in the pin bores, a detail that ensures the wrist pin and small end of the connecting rod stay well-lubricated, which is key for a long service life. The pistons also come with an accumulator groove to help maintain consistent ring seal and power, and each set includes premium rings, so you don't have to source them separately. Plus, the ArmorGlide skirt coating helps reduce friction and noise, while also cutting down on wear to the piston skirt and cylinder wall.

This set is for a 4.040 inch bore with a -5.7cc flat top dish and a 1.000 inch compression height, using a 0.927 inch wrist pin. Keep in mind these are not CARB approved and cannot be shipped to California.
