How do you beat a slew of Fox-Body 5.0 Mustangs that seemingly dominated the roads in the late '80s? You take a 454 cu.-in. big-block engine and stuff into a C4 Corvette and call it "Big Doggie". An experimental vehicle used to determine how to convert from a small block to a big block. Its 454 big block V8 along with its orange paint make this high horsepower engineering study a one-of-a-kind standout in Corvette history. The car had as much HP as the '90 ZR-1 did and it was named "ZR-2" or "Big Doggie". Old dog, new tricks joke?
The early C4's had their problems, what with the 1984 Cross-Fire Injection and its unusual 4+3 manual transmission. By the late 1980's, the fourth-generation Corvette had evolved into a more desirable automobile, thanks in part to the arrival of the ZR-1. 
1984 L83 350CI V8 Engine
The C4 Corvette debuted to a frenzy of publicity and would ultimately enjoy a lengthy run, spanning 13 years of production. During this period, GM installed a number of memorable powerplants. Many of these engines proved to be quite innovative in design, even when saddled with newly-mandated emissions equipment of the era. The following is a comprehensive guide to powerplants of the C4 era.
ZR- World Record Endurance Run Corvette on display at NCM
On March 1-2 1990 a unique group of people using a Chevrolet Corvette ZR-1, reset The 24-hour World Speed Record. That achievement proved unequivocally that the car is indeed...King of the Hill. "The 24" had stood for 50 years. Last set at Bonneville in 1940 by AP Jenkins driving the "Mormon Meteor Ill", a purpose-built. single-seat race car with an aircraft engine. The objectives: set the 24 as well as 5000 kilometer and the 5000 mile marks with a ZR-1 while using an L98-powered Corvette to set the six-hour record and other shorter distance marks.
1989 Corvette
For the first time in several years, the 1989 model year would actually see an increase in the total sales numbers of the Chevrolet Corvette. Chevrolet sold a total of 26,412 Corvettes in 1989.
In the late 80s, Chevy was developing what some dubbed a ‘Super Vette.’ But the 1989 debut of the Dodge Viper sent GM engineers on a new path to develop a ‘Viper-Killer.’ It started with a factory test mule and the experiment was to see how a ZR-1 would perform if given more power and less weight. It was so fast it was called "Snake Skinnner", for it's ability to beat the Viper and Cobra.
When Dick Guldstrand introduced the GS80 series in 1986, the car was targeted specifically at Pro-Solo and autocross enthusiasts. He knew all about the needs of these groups, as he was a longtime provider of performance upgrades for the C3 and a direct supporter of a small team of racers from the Western Council of Corvette Clubs. Up to this point, Dick had basically been a tuner. With the intro of the GS80 he was venturing into the realm of small-volume manufacturing.
