94MoostangGT

I was running my street tires. I was just wanting to see how it would do. The traction problem on the only 60 ft time I had I knew was a problem, but like I said by the end i was running about a tenth faster than that time. Does anyone else have a 94GT that knows what it runs? I guess it is possible that he had more done than he said, but for that big of a difference it seems like there might be something wrong with my car. Yes it is a 5.0 and and is a manual.
