We are running almost the same thing, it took me almost 10 years and 3 diff motors to come up with this combo. I have a few more mods, thats just all I could fit in my sig. 11.5:1 comp. BBK cold air intake, Diablo turner, no ac or smog pump, underdrive pulleys, Hurst shifter, windage tray, DSS main support system, Megabite Jr lower control arms, Kenny Brown subs, Ebiach drag springs, Lakewood drag shocks, Lakewood 90/10 struts, 6pt cage, 150 shot. Off the top of my head I think thats about it. Panhandle Performance did my dyno work. Its pushing about 350 on the motor and just over 500hp on the bottle. My best time in the 1/8 has been an 8.02 on motor and 7.21 on the bottle. There is no 1/4 track near where I live so I have only been on one a couple of times but I know it will run low 11s. The funny thing is that I used to have a red 89 gt that looked just like yours. Saleen wing 2 1/2" cowl hood and cobra r rims.
