High Performance Pistons
Click HERE to view our rotating assemblies using these Pistons
After many years of working closely together, Butler Performance and ROSS Racing Pistons have developed a new line of Performance Forged Pistons for traditional Pontiac engines base on a new Butler exclusive forging. For years piston forging designs used by performance piston manufacturers have been based off Small or Big Chevy, Ford, etc. When making Pontiac pistons, these companies would typically use a raw forging originally designed for a small block Chevy, being the closest thing to Pontiac bore size, valve spacing and order, etc. This has worked for many years but sometimes resulted in pistons being heavier than needed because the Pontiac designs didn't "fit" the Chevy style forgings perfectly. Now ROSS Racing Pistons has designed a true "Pontiac" forging exclusively for Butler Performance.These pistons are some of the lightest and strongest available, with no special internal milling required to get the reduced weight.
These are the latest "strut-style" design, which lends to the reduced weight as well as increased strength. These pistons can also be run at tighter piston to wall clearance so they are great for performance street applications as well as all-out racing.
Unlike many other vendors, our ROSS pistons for the long rod assemblies IE: BU65532, BU75628, BU70470
DO NOT REQUIRE OIL SUPPORT RAILS.

ROSS / Butler Custom Pistons
High performance pistons from any manufacturer are only as good as their designer. BP has spent years of dyno and track testing to develop our current designs. BP stocks several popular pistons by ROSS. We can design a custom piston for any application if one of the pistons listed below will not fit your needs. Allow approximately three weeks for custom orders.
Due to the volume of Pontiac pistons we order through them, ROSS has now developed dedicated Pontiac forgings for us. Therefore our ROSS pistons feature the lightest weight possible in relation to bore size, and all ROSS pistons are made with 2618 - T6 forgin
Piston price does not include the price of pins.

Keith Black Icon Forged Pontiac Pistons
Includes Pins and Locks (can be used with Bushed(full float) rods or Press-Fit rods
Keith Black introduces their new Forged Icon Pontiac Pistons. They use a high quality forging that results in a much lighter piston than the Federal Mogul/TRW. The pin is also quite a bit lighter than the TRW. These pistons come with pin locks so they can be used with BUSHED or PRESS-FIT rods.
