Rated to 450HP, these converters are engineered to work with mildly modified vehicles with non lock up transmissions. Modifications such as small camshafts, headers, intake manifolds, and other bolt on type mods work perfect with this converter. Not recommended for nitrous use. We have designed these converters to provide an economical performance option with no compromise left to chance. Equipped with Torrington bearings, hardened impeller hub, race prepped spray, hardened turbine hub and splines, hardened new steel pilot, and a dual GM bolt pattern laser cut mounting ring.
