I will take a look...lol. Both my black roadster and the blue coupe run high 11 quarters. Roadster 11.98, coupe 11.76.... I have a posi-trac rearend in both cars. This was built by a company in CA. Wavetrac. Other mods are listed in the sig. You stated you didn't like the grand national, and these cars are comparable. You may not like them. The MB side of it, makes shifting smooth, not harsh, and not when you want them to, but when they want to . It does have the option of the "slap" shifter, but it will shift at it's pace. They still are quick out of the hole. My best 60' was 1.76... Right now, I am looking for a way to change the coupes rear end gearing and TCU shift points, but that hasn't been perfected. So, you have a LOT of homework to do and read thru many of the threads. If you want to talk...just PM me and I will give you phone numbers. A handful of us have worked on modding these cars for the past 6-7 yrs.
