Yeah the '02's have a 3650 but they aren't much better than a T-45. The T-56 6-speed is a damn good tranny other than the fact it's a helluva workout to get it into reverse. If you want run low 10's go with some steeper gears, full exhaust, and a Procharger D-1SC. The D-1SC is THE best blower for a hardcore street/strip application and can easily provide 20 PSI. Obviously with all this power your going to need a stronger rotating assembly and if your going to do that you might as well get the SHM 300 c.i.d. stroker to add a few cubes. Hell, if you're going this far have your heads fully ported (or buy some race heads) and throw in some blower cams and you have one fast modular. I just hope you have a fat wallet though as it won't be cheap.
