SBC Domed Piston Set 4.060 Bore +8cc

The SBC Domed Piston Set 4.060 Bore +8cc (Part Number PTS502A6) is a precision forged piston kit designed for small block Chevy engines that require higher compression while maintaining pump gas compatibility. This piston set is ideal for street performance, bracket racing, and naturally aspirated engine builds where reliable detonation control is essential.

Engineered with a domed crown design that delivers +8cc of additional displacement per piston, this set allows builders to increase compression ratios without the need for exotic fuel blends or costly modifications. The 4.060-inch bore diameter accommodates standard small block Chevy block overbore tolerances, while the 1/16 x 1/16 x 3/16-inch ring groove configuration ensures proper ring seal and minimal blow-by across the RPM range.

This piston set is particularly beneficial for engine builders and performance enthusiasts looking to rebuild or upgrade small block Chevy platforms for increased horsepower without sacrificing fuel availability or daily drivability. The superior strength-to-weight ratios provided by Wiseco-Pro forging technology translate to reduced reciprocating mass and lower inertial stress during high-rpm operation.
