Description

Keith Black Hypereutectic pistons are a great choice for high-performance marine, drag race, circle track, street, or towing application builds. The low expansion 390 alloy with 16 percent silicon allows for a tighter piston-to-wall running clearance. This kit features a 4.020" bore and 11.20cc dome, designed for Chrysler 360 LA Small Block engines from 1958-2009.
