Thanks for the post guys, I am playing at the track just for fun, and like to compare.
I am running a 302 Naturally Aspirated motor on 275/40/17 street tires thru a T-5 w/ 3.73 rear end. My best time was 12.59 at 108.5. My weight distribution is 47/53 (I know, it surprised me too) at 2688# w/ me in it (big-ol 245# guy) and wet. I would like to see 12.3's just to mess with Hal
but I think that 12.4's are more realistic with the 302. I feel that I am not pushing the limit on the traction once I am off the line. More power could be used in 2/3/4 gears. First gear is a blink. It seems that the stroked 351's are able to get their extra time because of this greater ability to run closer to the ragged edge all the way thru the gears. Doing it all again, that's probably the way I'd go for road course and non-slick dragging. I am avoiding the slicks right now, cause this T-5 would most likely snap.
