Sponsored Links One of the rarest Corvette ZR-1 units ever built just sold for $75,000, which seems cheap considering its story. The 1984 model-year Corvette was a clean-sheet redesign, aesthetically speaking. It still carried the Cross Fire Injection 350 from the 1982 Corvette, which yielded 205 horsepower. In 1985, the Corvette received a performance upgrade in the form of the Tuned Port Injection L98 which churned out 230 ponies. As the years progressed, the L98 would see incremental power increases, but all the while there was something evil being developed. As so often happens with special Corvettes, the development of the new King of the Hill model was not a well-kept secret.
