Description

CHEVY LS SERIES -8CC FT 4.125" BORE

MIA's Description

Constructed from 2618 aluminum, it features a 4.125" bore size and a -8cc dome volume.

This piston is engineered with valve pocket designs that accommodate oversized valves and high lift cams, promoting maximum airflow. Its crown shape is optimized for intake charge efficiency, leading to increased horsepower. The dome design aids in optimal quench during the combustion cycle, reducing detonation and pre-ignition. Precision-machined ring grooves ensure maximum ring seal and minimize blow-by.
