440 CHRY DISH

These are forged pistons designed for a Chrysler 440 big block engine, specifically for a 496 cubic inch stroker build. They feature a dish design with -24cc volume, a 4.360-inch bore, 4.150-inch stroke, and 6.768-inch rod length. Made from high-silicon 4032 aluminum alloy, they are designed for reduced piston-to-wall clearance and quiet operation. Key features include accumulator grooves for improved ring seal, forced pin oilers for increased wrist pin lubrication, and redesigned valve pockets for larger valves and high-lift cams. The pistons come with pin fitting and double spiro locks. Rings are sold separately, accepting 1/16, 1/16, 3/16 ring sizes. Two wrist pin sizes are mentioned: 1.094 x 2.930 x .150 (170 grams) and .990 x 2.930 x .150 (150 grams).
