Your only engine option was an electronically fueled injected (Tuned Port Injection) Small Block Chevrolet with 350 cubic inches V-8 or 5.7 Liter/5735cc to be more specific for the metric types. It produced a net 245-Horsepower @ 4300-Rpm and 345 Ft-Lbs of tire-shredding Torque @ 3200 Rpm. Transmission options were either a 4-Speed Automatic with Overdrive or a 6-Speed Manual ZF (Zuffenhaussen).

Phillip I hate to disagree with you but the ZR-1 Corvette that debuted at the 1989 Geneva Auto Show was not just an "engine option" it was a "Model Specific Option" that included the LT-5 engine and a fully redesigned performance package. However, despite the unprecedented and overwhelming media coverage further promoting the arrival of the “King of the Hill” ZR-1 Corvette, it was announced by Chevrolet on April 19, 1989 that the ZR-1 would not be available as a "production model" until the 1990 model year. While both the media and Corvette fans vehemently protested the announcement, GM gave the reasoning that there was “insufficient availability of engines caused by additional development.” Eighty-four 1989 ZR-1 Corvettes were built for evaluation, testing, media preview and photographing, but no 1989 model ZR-1’s were made available for public purchase.
