When horsepower goals exceed conventional limits, the LSX engine becomes the foundation of choice. Developed for racers and serious performance enthusiasts, it offers unmatched block rigidity and strength. The iron construction resists flex under extreme boost, while its reinforced deck and six-bolt main design provide exceptional crankshaft stability. This makes the LSX engine ideal for turbocharged and supercharged applications pushing well beyond 1,000 horsepower. Builders appreciate its adaptability, allowing custom bore and stroke combinations that transform raw mechanical potential into reliable, repeatable power on track or street.
