There were three that could hit 200 in a mile, and 11 that were 154-185 mph. The three were the TT Viper at 210 mph, the TT Saleen S7 at 205 mph, and the Lola champ car at 203 mph. You have the HP of the Viper, or something close although he'll have you on torque, a few hundred pounds lighter, and much more aerodynamic. The Saleen and Champ car are lighter still.
Your car may have the power to make 200 mph, but not in a mile in my opinion. But I do not think you can control the car at that speed either without some big help in the air management area. I do not know what changes would be required, but HP alone will not get you there, at least not and live to tell about it. Your car is dangerous compared to most in that it has the HP to get you beyond what the car can handle. In other words, the standard 500-600 HP Chevelle would be limited to say 160 mph as he would not have the HP to push the car shape any faster. He might be near the limit as far as lift, etc. but not over it. Your car will push past that on power alone and will get into an area you do not want to be in.
The goal is cool (except for the street part) and I hope you pursue it. But please do it with the safety equipment required and work your way up in speed testing the handling and air management changes. I would be talking to the Bonneville guys as they go very fast in stock bodied cars of all shapes and sizes.

This is a very intelligent post. Jody knows what he's talking about. SW has been there too. I've been over 175mph numerous times myself,on bikes and in modified ZR-1's. Corvettes and Vipers are pretty stable and confidence-inspiring at ultrahigh speeds but I would be extremely careful working your way up with a Chevelle. If the car decides to fly,it can happen so fast you won't be able to get outta the gas in time.
FWIW,you will not need a 6spd trans to run an ORR. Most of the Unlimited class cars are running 4spds with 2.00-2.50 final drive ratios.
