Sikky Manufacturing hand built LS engines feature the best components and are assembled by professional machinists. All hand built engines feature a balanced and blueprinted block with forged internals. We also partnered with AFR (Air Flow Research) to equip these engines with CNC cylinder heads and Inconel exhaust valves. These builds have been track tested for maximum reliability and performance.
*Horespower numbers are at the wheels on a Dynapack dyno with stock LS3 intake manifold and throttle body, Sikky 1 7/8” headers, and Sikky 4” intake/filter*
