My car weighs 3490 w/o me in it and I ran a best of 9.6 @75 1/8 and a 14.8 @96 1/4 both with a 2.3 60'. I just got my 3.73's installed last weekend and need to go back to the track to work on getting my 60' lower.
loose weight (Free), sticky tires for the track ($400), stall convertor ($600), drive agressive. That should get you pretty well into the 14's. Then maybe an o/r H-pipe ($150), ligher weight front wheels/tires ($150 used), TB, MAF, somethng else...
