Product Description

Every Livernois Motorsports built short block is assembled by hand with the utmost attention to detail. Balanced and blueprinted with strict tolerances for quality, reliability, and performance unmatched in the industry! Livernois Motorsports has taken its experience in building winning race engines and applied that to its own line of performance engines for street/strip applications.
