Mark Up Another One For The Sho

So, Friday night, I went down to the local spot to watch some races and found myself participating. I was talking to a guy while watching some races and he said he had a Thunderbird SC and asked if I was interested in racing it. So, of course, I didn't back out. Now he said that the SC was stock except for the the exhaust, and last year he had a SC pulley on it, but took it off this year. Why, I don't know. So, I thought this might be a good time to try out the new clutch. We raced twice. The first one we both spun, but I regained traction before he did and put about 3 car lengths on him by the end of the 1/4 mile. We came back and he said he was manually shifting his auto and wanted to try it again. So we lined up again. We both had a much better launch and I immediately put 4 car lengths on him through 1st and 2nd gear and kept it till the end. Does anyone know what a "stock" SC runs in the quarter mile? I knew that it should be a great race for the stock SHO. But I thought it would have been a closer race at the end. Maybe it all just came down to the drivers. Any info would be great.
