Any Mustangs Race a Cadillac STS or any Northstar Engine?

I have raced a black STS, one of those stoplight things where the guy pulls up and revs it. I know I shouldn't have on the street but I couldn't help myself. They are pretty quick cars for a large car but I wish I would have had a camera for the look on his face when I went by him. I had to give him the take off due to traction issues but when she quit spinning in second I went by him like he was sitting still. Oh, that was before the supercharger. Now I would just be wasting my time without some Micky T's on the back. 1st, second and third are useless on regular radials.

My brother owns a CTS. I have raced him a couple of times and beat him very easily.
