BBC 502 Domed Piston Set 4.600 Bore +46cc

The JE Pistons BBC 502 Domed Piston Set 4.600 Bore +46cc is designed for serious big-block Chevy engine builders who are focused on high-compression, naturally aspirated powerplants and moderate boost applications. This piston set is suitable for both enthusiasts and professional shops, delivering the structural integrity and precision geometry necessary for elevated combustion pressures.

Crafted from forged aluminum alloy, this piston set is engineered to resist thermal distortion, micro-welding, and premature wear, making it ideal for high-RPM operation or turbocharged applications. The domed crown profile is specifically designed to increase the compression ratio, enhancing combustion dynamics without requiring costly block modifications. This ensures optimal fuel mixture distribution and peak power generation across the RPM band.

Ideal for builders developing 496–502 cubic-inch BBC engines, this piston set is perfect for those targeting a compression ratio of approximately 10.5:1. The 4.600-inch bore specification ensures a perfect fit within a standard-stroke or stroker configuration, making it a reliable choice for both street performance and racing applications.
