The flat-top crown has a -3 cc volume specification to support precise compression-ratio planning when paired with the appropriate cylinder head, gasket, and rotating assembly components.\u003cbr\u003eThe 139482 set includes eight pistons with ring grooves sized for 1\/16-inch, 1\/16-inch, and 3\/16-inch rings. This configuration helps accommodate common performance ring packages while maintaining compatibility with properly matched engine components. Forged construction offers the strength and durability needed for demanding street, racing, and high-performance applications when installation and clearances are correctly verified by the builder.\u003cbr\u003eDesigned for Big Block Chevy engines, these Sportsman Racing Products pistons are intended for builders who need a consistent piston set for a large-bore combination.
