I was wanting to do the same thing a year or so ago. I have a 94" mustang cobra (Don't shoot me I also have a 55 PT belair I'm building) with a dart based sbf 356 cubic inch with all the goodies billet bottom end, afr heads, solid roller, jesel setup, Fast XFI, etc... and a 88mm turbocharger. This is in a car that has every suspension piece that maximum motorsports makes (killer mustang suspension). I had talked to a few guys that had run their cars at serious speeds and was definately educated on the facts of aero and downforce. Like you "Nitrorocket" I thought it would be no big deal to do 200mph (1000+ rwhp) and I had already gone 155 or so with a small turbo and stock motor. When I realized what it would take to do 200mph I was shocked. Just look at the newer cars that are 200mph capable or close and you'll be amazed at what they have. It takes finesse to get a car that fast and be able to be controlled. These cars all have some major things in common besides a slippery outside.. They all have ways to get air out from under the car and prevent most air from getting there in the first place. These cars have good downforce and not a lot of frontal area. I think you could get your chevelle to do it but go drive a new Z06 or even a srt10 viper and then study the car a little and you'll understand what I am saying. The horsepower is there the other larger part to the equation will take some serious work. Good luck
