2019 C7 ZR1 Corvette: The King Is Back! Of course, only the Corvette engineering gods have driven the new ZR1, so us mere mortals will have to wait and be satiated with images and words. The Car and Driver December 2017 story quotes Corvette chief engineer Tadge Juechter describing the ZR1 as, “… the most we know how to do…” He also describer the ZR1 as, “… a high-powered grand touring car.” Yes indeed, GRAND!

It was a cold, windy, overcast, nasty in Texas on the day of the record run. The timed event started at 9:55:12am on March 1, 1990 with John Heinricy at the wheel of the ZR-1 and Tommy Morrison driving the L98. The pace was essentially flat-out! Heinricy said, “Speed was in the low 190s. We didn’t lift in the turns. We entered them foot on the floor and by the time we came out of it, we’d be in the high-170s. It didn’t slow down much in the turns.” Fuel stops only took about 45-seconds to fill the 48-gallon fuel cell. Interestingly, the chassis and tires weren’t really stressed that much by the low cornering loads – something that would have been an issue at one of the high-banked tracks. Read More
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. Read More
While 3-deuces had been around for over 10 years on Pontiacs, seeing that big triangular air cleaner atop of the already enormous big-block stuffed into the ‘67 Sting Ray was almost better than a Playboy centerfold! Read More
