looked like 12? mph through 4 or 5 gears not too bad but need improvement... a 3.73 gear would wake that bitch up and still do 165+mph with intake,headder back pipes, upgraded stall, and a 3.73 my vette ran 8.50's at sunshine on street tires and it did 170mph on a certian stretch of bridge the will remain unnamed.. its on video i have to dig it up.
