Show original supplier description
The Speed-Pro SEAH336CP30 is a set of eight hypereutectic pistons engineered for Small Block Ford applications. Constructed from an aluminum alloy with 16% silicon (FM244), these pistons offer enhanced strength and wear resistance. They feature a 4.030-inch bore, a flat top design with machined valve reliefs, and a -12.00 cc volume, contributing to a specific compression ratio. The pistons utilize 5/64-inch top and second ring grooves and a 3/16-inch oil ring groove. Sophisticated "barrel" profiles are incorporated to optimize the oil wedge between the skirt and the cylinder wall, while the piston skirts are protected by a DUROSHIELD coating for extended life and reduced friction. These pistons are weight-matched to within +/- 2 grams, ensuring balanced engine operation. The included wrist pins are of a floating/press style with a 0.912-inch diameter, and LR-63 lock rings are provided for floated applications. The hypereutectic material and coated skirt contribute to their performance and longevity in demanding conditions.
