1967 1968 1969 Camaro 302 pistons

[Dwight Southerland]

You can use the OEM replacement pistons and they were produced by TRW. However, TRW never made an aftermarket piston that matched the specs of the OEM pistons. Their only aftermarket offering was a piston with a much larger dome yielding 12.5 to 1 compression. Since you could buy the replacement pistons from GM, they saw no need to duplicate it in the aftermarket.
