Ah damn, you're right. I was thinking they kept that older motor setup for one more year, it was the '84 Vette that was a total dog (for a V8, even more so for carrying the Vette name). I do know one thing, being a former driver of a 100% stock '96 GS LT4, that chassis and overall vehicle balance is prone to flash oversteer. After driving an even more powerful C5 Z06, I was amazed at how much more composed the Vette had become.
I also gave the SVT Contour too much credit perhaps, I thought it was somehow close to the SVT Focus, which puts down better slalom times than same-era Vettes, Boxsters, etc.
