SRP big block Chevy high-compression dome top pistons have a hollow dome design that fits most open chamber STD GM, Dart, and Brodix heads. They are forged from premium 2618 aluminum alloy with CNC-machined domes with radiused valve reliefs that provide optimum flame travel. They include a pin fitting, double Spiro locks, and a wall wrist pin. Their CNC-machined ring grooves accept 1/16, 1/16, 3/16 rings, which are sold separately. These pistons will fit tall decks when used with .400 in. long ends, but will not fit GM Signature series or Edelbrock cylinder heads. Pin upgrades are available.
