This is my 97 gt and me. I have put a custom x-pipe and cat back with 40 series flows. rebuilt tranny with a Steeda Tri-Ax short throw shifter, 3.73 gears, aluminum flywheel and driveshaft Steeda cold air intake and a trick flow upper plenum. I have run a best of 14.7 at 98 mph. I plan on stroking my engine out to a 5.1 so if any of you have done this before inform me how much of a pain in the ass it is.
