Description

Forged pistons for Chevrolet Small Block 381ci engines. Specifications include a 4.020-inch bore, 3.750-inch stroke, and compatibility with 5.700-inch rod length. These pistons feature a flat-top design with 11cc domes, designed to achieve approximately 12.2:1 compression with specific cylinder head and block deck height configurations. They have a compression height of 0.976-inch and a lightweight design (414 grams with pins), using narrow JE rings (0.043" for compression, 3mm for oil) to reduce friction.
