I don't know how much chevrolet did exactly but a good friend of mine had a 90 iroc when I bought my 92 b4c. he made the mistake of letting another friend of mine borrow it for some ungodly reason. well to make a long story short. we line up and my friend flags us and were off instantly i had a easy 3 cars on him off the line and by the end of a short quater it was very ugly. My car as it was, was completely stock down to the paper air filters. at the time it ran a 14.2 @99. but then again it hooked like a mo fo when it was stock hope this helps.
