These Icon pistons feature a diamond-machined skirt, head, mini-grooves, pin bore, gas accumulator, ring grooves, and pressure-drilled pin hole oiling. They have a V-rib design for light weight, strength, and maximum piston cooling.

Use OE and Edelbrock style heads. Some stock rods may need to be narrowed and balance pad removed.

Icon Line of Forged Pontiac Pistons by Keith Black 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.
