Finally, a 392 piston designed to handle boost! These new drop ins from HHP have all the features that we use in our high boost engines. Designed to use the OEM head gasket, we've eliminated the need for custom pushrods and head gaskets.
Our exclusive combination features a 9.7:1 dish piston made from the highest quality 2618 material from Ross with strutted skirts for less piston deflection under boost. We've added 0.180 wall pins to deal with deflection and steel rings for proper ring seal in boosted applications.
