351W INVERTED DOME

Most of these pistons are designed to be compatible with forced induction and nitrous applications and will accommodate larger valves and long duration, tight lobe separation cams. New parts have been designed to suit the large bore after market race blocks and the T.F.S. "Twisted Wedge®" cylinder heads. All block deck heights have been adjusted to reflect zero deck clearance and precision CNC ring grooves accept 1/16, 1/16, 3/16 rings.
