The Speed Pro H534CP30 engine piston set is engineered for performance applications, offering a balance of power and value. These pistons are manufactured from hypereutectic aluminum alloy, known for its strength and wear resistance. Each piston features a flat head design with four reliefs and is coated with DUROSHIELD on the skirt for enhanced durability. This set includes eight weight-matched pistons, along with the necessary pins and lock rings. Key specifications include a bore diameter of 3.766 inches, an oversized measurement of .030, and a compression distance of 1.560 inches. The piston pins measure 0.927 inches in diameter. The ring package contains two compression rings (top and second) with a thickness of 0.0781 inches and one oil ring with a thickness of 0.1875 inches. The dome volume is -5.0 CC. The application summary indicates compatibility with a range of vehicles for performance engine applications, including various models from Buick, Chevrolet, Oldsmobile, and Pontiac spanning from the mid-1970s to the late 1980s.
