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. These builds have been track tested for maximum reliability and performance.
