This is a set of forged Pistons made in California to my specification by Ross. It has a very specific combustion shape to make them very detonation resistant, an important feature for engines intended to run on automotive fuel. The kit includes forged GM rods rebuilt with ARP bolts, Rebored Corvair Cylinders, Chrome rings, copper base gaskets, and the pistons. This bore does not require machine work to the engine case. The set comes fully assembled. All components are made in USA
