Well, the owner is on this board (
Buizilla) and I think he told me the car regularly 60 foots down in the 1.8s, and did a 1.84 at Bristol, but the air was crap, and he was 3-4 mph off...yet he ran 12.1s!
HERE is a thread about his recent runs. So, you do the math...
It's an auto, no idea on cubes, but he says it's under 400. As for weight, it's probably relatively light, but the car runs a full interior, and has to remain a stock appearance, so it hasn't been "stripped".
