ORSCA has come out with a new street car class called Hot Street designed for REAL street driven cars with power adders. Pretty interesting rules too. Ron at Vengeance Performance deliberately pissed quite a few people off when he would NOT allow carburetors or aftermarket ECM systems into the class. Personally.....I like the guy already. 
I really wanted them to keep the idea of requiring an overdrive transmission but they weenied out.
I'm thinking this could be a damn good deal for a lighter weight S197 or a 3V/Fox or 4V/Fox conversion. Getting an S197 down to competitive weight would be problematic....but then again.....maybe that's not a big deal after all. PLstang's car, Adam at ST, and the Chevykiller are mid-nine second cars and they're over 4000 lbs. Get one down to 3500 with the driver and you've got one hell of a good chance at winning. The Fox conversion would be a friggin' runaway. The only bitch I have with this whole deal is adding weight every time you win or runner-up. With seven to eight races on the schedule you could end up with a 4200 lb car if you managed to win them all.
We figure this should be a mid-low 6 second class (remember, ORSCA is 1/8th mile only). Granted....I'm figuring a few high 5.90's from time to time so you need to be able to put down a run once in a while. Right now, my car is 7-flat capable with a stock engine on eight psi and 3820 lb race weight. Figure a 298" Livernois setup (or even a big bore) with 16-18 psi and 3600 lbs race weight just might be competitive. If not.....fuck it. I'll find a decent Fairmont Futura and do a 5.4 4V GT500 engine swap with my turbos at the same boost and a Turbo 400 or a 4R70W.
Here are the rules.
