In 1992, base Corvettes now used the LT1 engine. With major changes between that engine and the earlier L98, Callaway shifted from positive manifold pressure to increased displacement with the new SuperNatural series. Introduced with 400 hp, power climbed to 425, then 435, and finally 450 hp for the LT1 and LT4 cars. During this same period, Callaway also built SuperNatural Corvettes based upon the ZR-1 Corvette and the LT5 engine. Introduced with 475 hp, power was also available with 490 hp with optional header cats. A full menu of options (brakes, suspension, exhaust, body, wheels/tires) were available. Originally, the SuperNatural Series was called the CL-1 and CR-1 CL, for the LT1 powered cars. CR, for the LT5 powered cars. This moniker was very short lived, changing to SuperNatural soon after introduction.
