HI-TECH HYPEREUTECTIC HIGH PERFORMANCE SMALL BLOCK CHEVY 302 PISTONS are fully designed, tested, and certified by a QS-9000 and ISO-9001 OE manufacturer with 30 years experience in piston manufacture for the OE's and the performance racing market. Cast with 16-18% silicon HI-TECH HYPEREUTECTIC HIGH PERFORMANCE PISTONS are fully designed, tested, and certified by a QS-9000 and ISO-9001 OE manufacturer with 30 years experience in piston manufacture for the OE's and the performance racing market. Cast with 16-18% silicon alloy, hypereutectic pistons are T-6 hardened, suitable for even very high performance applications. Precision machined super high performance piston with original dome design for all 302 engines, stock compression ratio (11:1 with 64 cc heads). The new tooling was specifically made for our pistons and specific machining cams were produced to accurately machine the profile and taper. (Many manufacturers just have a few generic cams and they pick the closest one). Each alloy batch is independently tested and certified before casting and then hardened to specs under computer control. EXCLUSIVE computer designed under structure allows dome machining (0.143") to safely reduce the compression ratio to 10:1 and maintain balance. Free floating wrist pin and spirolock retainers included. Sorted in sets of eight by size and weight to balance and blueprint tolerances. {+/- .0004" and 1.5 grams or better}.
