Precision-machined high performance pistons with original dome design and floating wrist pin for 2nd design 1968 and 1969 stock compression 302 engines (11:1 with 64 cc heads). Cast with 16-18% silicon alloy, and T-6 hardened for performance applications, new tooling was specifically made for these pistons featuring an exclusive computer-designed understructure allowing dome machining (0.143") to safely reduce the compression ratio to 10:1 while maintaining balance. Warranted fo r 2 full years in street cars. Wrist pin and spirolock retainers are included. Individually plastic-sleeved after factory sorting in sets of eight by size and weight to balance and blueprint tolerances (+/- .0004" & 1.5 grams or better). Important: Piston rings not included. Not recommended for extreme performance engines. Note: These hypereutectic pistons will also fit 1967 and 1st design 1968 engines with no modifications.
