Show original supplier description
The Keith Black KB362.020 is a set of hypereutectic pistons engineered for performance builds in Chrysler 360 cubic inch engines. Designed with a 4.020-inch bore and compatible with a stock 4.000-inch stroke, these pistons are built for durability and increased compression. Each piston in the KB362.020 set is crafted from a high-performance cast hypereutectic alloy, known for its superior thermal barrier properties and lower thermal expansion compared to traditional cast pistons. The pistons feature a step head design with two valve reliefs to accommodate valve lift, and a +19.4cc crown volume that contributes to a higher compression ratio. The specified rod length for this application is 6.123 inches. These hypereutectic pistons are suitable for a variety of demanding applications, including marine, drag race, circle track, street, and towing builds. They offer a lightweight yet robust solution for engine enthusiasts looking to enhance performance and reliability in their Mopar Small Block LA or Magnum engines. They are available in various oversizes, including STD, .020, .030, .040, and .060.
