i havent had it to the track, this summer i hope, but i do have a g-tech pro comp and did an 11.4 @ 123 on nitto 555 d/rs...shifting at 5800.. i run 355 rear end and factory 5 upper and lowers...steeda tri ax and spec 2 clutch..alluminum drive shaft...so if you can get traction, a 331 with the same set up and you should be in the 10s. ps my car is also a tank i have every kind of brace and a roll bar, plus 200 lbs of stereo equipment so get rid of that and faster yet...
but i do think i get better traction with it , so i dont know?...
