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.


Drop In 2618 Ross Piston 9.7:1 Compression for Stock Bore 392 made exclusively for HHP Custom Manley Rods w/ ARP 2000 Rod Bolts made exclusively for HHP Advanced Profile Total Seal Rings Tool Steel Wrist Pins No Balancing Required! Addition of valve reliefs to accommodate larger cam profiles and larger valves (2.165 intake of the Thitek's) - Oil Squirter Plugs Included
