New 20° BBC Series Pistons Available from JE Pistons

After developing a multitude of custom pistons for big-block Chevrolet engines equipped with 20° cylinder heads, like the Dart Pro1 20° and Brodix SR20, the engineering team at JE Pistons has created the 20° BBC Series that combines high quality custom piston features with off-the-shelf convenience.

The pistons are available with 23cc and 18cc domes, designed for high horsepower naturally aspirated and nitrous engines with bore sizes from 4.600″ to 4.625″. Forged in-house from 2618-T6 aluminum, they incorporate many special features that elevate these new 20° pistons above the norm. They include JE’s Ultra- Groove process that creates flat and smooth ring grooves with tolerances held to a millionth of an inch, and vertical gas ports providing a consistent ring seal. Special contact-reduction grooves reduce friction and minimize detonation, while the power adder accumulator groove provides increased accumulator area without weakening the ring land.

The dome incorporates a fire slot for improved flame travel and combustion efficiency, and is designed to accommodate up to 2.450″ diameter intake valves, while the underside is 3D crown-milled to remove all unnecessary weight and reduce the reciprocating mass. Optimum wrist pin lubrication is assured through employing a broach pin oiler with an accumulator groove.
