Livernois Motorsports shortblocks are put through grueling test sessions on the dyno where our stroker engine package was first developed. Then hours of rigorous track testing was done to make sure we had a bulletproof package.

Every Livernois Motorsports built Rotating Assembly or 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. From deburring and radiusing the blocks and pistons, down to the environmentally controlled clean room assembly procedures, Livernois Motorsports is confident that it is providing the customers with the highest possible quality in every engine that is built!
