Shooting for 12s with stock runnered TPI

I am going to try to break into the 12s with my TPI this Friday. I have ran a best of 13.4@103.5 but have MPHed as high as 105. I am going from a 2200 convertor to a 3500. Will it do it? I hope so! We shalll see! What do you think?

Assuming same everything but torque converter, I don't think you'll hit 12's, but hey, it could happen!

Going from a 2200 stall to a 3500 stall is a big jump!! You should notice a big difference in the car off the line. My guess would be that you will run 13.0's all day, and maybe on that perfect pass you will squeeze a 12.9999999. LOL
