1984 PPG Indy Pace Car
The 1984 PPG Indy Pace Car Corvette was special from the very beginning- in several ways. Initially, it was created as a one-off concept car that would be designated as one of the official Pace Cars for the PPG Indy Car World Series of races. It was custom-built by PPG in cooperation with the Chevrolet Division of General Motors. The 205 HP 350 was replaced by a 450hp, 401 cubic-inch V-8.
These Big Block cars would be the high-water mark of Corvette performance and refinement for the C2 series of cars. The 427/400hp L68 came standard from the factory with the Holley triple two-barrel carburetor arrangement called Tri-Power. Only 2101 Corvettes in 1967 received this rare engine option which was a $305.50 cost.
The L71 was Chevrolet’s most powerful engine in 1967 which replaced the big-block L71 from the previous year. Using it’s famous ‘Tri Power’ intake manifold was rated by the factory at 435 bhp. Costing $437.10, 3,754 Corvettes were made with the L71 options and they could not come with automatic transmissions nor air conditioning.

For more than a decade after the Corvette's initial release it had small-block power. In fact, the 265 cubic-inch V8’s 1955 introduction was largely responsible for the Corvette’s validation as a sporty, performance-minded vehicle. However, by the mid-1960s, those behind the scenes at Chevrolet had begun developing a new powerplant. This engine would become the first big-block V8 to be used in Corvette production.
