The fourth-generation Corvette was the first complete redesign of the Corvette since 1963. Production was to begin for the 1983 model year but quality issues and part delays resulted in only 43 prototypes for the 1983 model year being produced that were never sold. All of the 1983 prototypes were destroyed or serialized to 1984 except one with a white exterior, medium blue interior, L83 350 ci, 205 bhp V8, and 4-speed automatic transmission. After extensive testing and modifications were completed, it was initially retired as a display sitting in an external wall over the Bowling Green Assembly Plant's employee entrance. Later this only surviving 1983 prototype was removed, restored, and is now on public display at the National Corvette Museum in Bowling Green, Kentucky. It is still owned by GM. On February 12, 2014, it was nearly lost to a sinkhole which opened up under the museum. Eight other Corvettes were severely damaged.
For the 1992 model year, the 300 bhp (220 kW) LT1 engine was introduced, an increase of 50 bhp (37 kW) over 1991's L98 engine. This engine featured reverse-flow cooling (the heads were cooled before the block), which allowed for a higher compression ratio of 10.5:1. A new distributor was also debuted. Called "Optispark", the distributor was driven directly off the front of the camshaft and mounted in front of the timing cover, just above the crankshaft and harmonic balancer. Also new for 1992 was Acceleration Slip Regulation (ASR), a form of traction control that utilized the Corvette's brakes, spark retard, and throttle close-down to prevent excessive rear wheel spin and possible loss of control. The traction control device could be switched off if desired.
Here we have a wonderful representation of the C4 with the LT1 engine. Additional features of this kit are listed below.
