Stop light to stop light, and 1/4 mile are two very different things. On the street, (ie stop light to stop light) You should be able to kick some asz. The SC's has a huge torque advantage, which should get you out of the hole quite a bit quicker. The Buick won't have enough room to really get that engine up and running before you have to slow down. You see what I'm saying?
I did beat a stock '99 GTP a couple of times. I'm not really sure how though, now that I think about it. At the time, I had a K&N filter and exhuast. We went out to a closed highway, marked out a 1/4 mile, and went at it. I spun like a bitch out of the hole, and he got 1-2 car lengths on me. Now here is the wierd part. About half way down, I pulled on him like a bizitch and blew past him and ended up about 1-2 car lengths in front. Yeah, I know, isn't that just wrong. I was surprised to that I pulled on him that hard on the top end. The GTP did have to have it's tranny rebuilt the next week, so that might of had something to do with it. AND, he was kinda an idiot and was doing burnouts and donuts, and stuff for about 20 minutes before I showed up, so that couldn't of helped him. I don't know, we did it twice and had the exact same result both times.... I was going to race my friend in his '67? Chevelle 327, but the cops showed up and we had to scattered. Oh, and this other kid had a beat down pos '86 Supra with 180K miles on it and was always talking crap. I was going to smoke him also, but like I said, the cops showed up. Anyway, that was back when I was really stupid.(ie 17 year old in high school with 315 ft. lbs. of torque). Anway, sorry about the length, I was just reliving the past.......
