1976 Chevy Camaro - Project g/28 Part 4
The pistons in our Lunati kit are forged from 4032 alloy, a mix of aluminum with a higher silicone content than full-race pistons. This material specification significantly reduces the thermal expansion, allowing tighter piston-to-wall clearances, and quieter running, especially when cold. The valve pockets are extra deep, and provide the clearance to swallow much more lift and duration than our emission cam will deliver. The combination of this piston and the SysteMAX heads 68cc chambers provides a compression ratio of 10.6:1 at zero deck.
