BBC 502 Domed Piston Set 4.470 Bore +1cc

The BBC 502 Domed Piston Set 4.470 Bore +1cc from Sportsman Racing Products is an essential component for Big Block Chevy engine builders focused on high-compression racing applications. Designed for serious competitors, these domed pistons enhance combustion chamber efficiency and detonation resistance in BBC 502 engines. Ideal for circle-track, drag racing, or marine powerplants, this piston set is tailored to maximize performance.

Engineered with a domed crown design, these pistons increase combustion chamber volume reduction, raising the static compression ratio and promoting faster flame propagation. The 4.470-inch bore diameter is specifically designed to accommodate the oversized stroke combinations typical of 502-cubic-inch BBC builds. The precision forging process ensures uniform material density, superior fatigue resistance, and thermal stability under high-RPM conditions.

This piston set is particularly beneficial for engine builders constructing competitive BBC 502 power plants for dirt track and bracket racing. Each piston maintains tight tolerances to minimize blowby and reduce friction losses, ensuring consistent ring seal across all cylinders during peak performance. The BBC 502 Domed Piston Set is a reliable choice for those looking to enhance their racing engine's capabilities.
