Classic Industries Restoration Parts and Accessories - Bottom End

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.

NOS (new old stock) GM main bearing set for big block engines. GM part number 12329723.
