Back about 3-4yrs ago when I had my stock longblock with pullies, K&N, 3.73's, and 125shot at the track I raced a 12.8 lt1 maro' at GIR. My car was REALY stock looking/sounding and his car was loud from dumps and had no pass seat. We staged and ran. I ran a 13.1 @ 107 with a 1.9 street tire spinning 60ft. to his 12.8 @ 104.
I got a chance to talk to him later and he said "man I thought from the way that car was setup I would be out in front by a long shot" thinking I was stock. "At about mid track I looked back thinking you would be far in my rearview but you were right at my rear quater and I just thought holy cow thats a running mofo" He had me beat by his reaction time, first 60ft, and 330 or whatever it is market as. but had I not been sleepin and/or on the street from a slow roll he said I would have had him and I agreed'. He cut like a 1.6-1.7 60ft IIRC on DOT's.
That was prob. my funnest race so far at the track...
