Vette Videos: 1992 C4 ZR-1 Corvette Promotional Video
Even though the big news for the ‘92 Corvette was the LT1 350 engine with 300-horsepower (a 50-hp jump from the previous L98 engine), the 375-horsepower ZR-1 continued to get most of the attention. The ZL-1 and it’s LT5 engine had proven itself in March 1990 when the Morrison Motorsports ZR-1 shattered a 50-year 24 hour average speed record, recording an astonishing 175.885-mph speed!
The engine was so stout that engine builders, such as Corvette racing legend, Kim Baker, were building LT5 engines that were pulling horsepower figures in the low 600-plus range, WITHOUT the use of turbos, roots, or centrical superchargers! The LT5 was arguably one of the strongest engines to ever work under the hood of a Corvette.
