SBC Dome Piston Set 4.030 Bore + 12.7cc

The SBC Dome Piston Set 4.030 Bore + 12.7cc from Race Tec Pistons is specifically designed for small-block Chevrolet builders focused on high-compression and high-RPM performance. This piston set is ideal for applications requiring precise compression ratios, such as forced induction and naturally aspirated race engines.

Featuring a 4.030 bore diameter and a 12.7cc dome volume, this piston set enhances combustion efficiency and allows for fine-tuning of static and dynamic compression ratios. The dome design raises piston crown volume, which is crucial for optimizing performance based on fuel type and camshaft profile. Manufactured to OEM tolerances, these pistons include premium ring grooves and cooling galleries for reliability under high-load conditions.

Engine builders will appreciate the precise bore sizing that matches stock or honed cylinders, ensuring a better fit during assembly. This set is particularly beneficial for those working on custom builds within short-deck, billet, and traditional SBC platforms. By focusing on exact specifications, builders can achieve their desired performance outcomes without unnecessary complications.
