You should be able to get a good mid 12 with that mph. I was running 12.44@107.
Looks like the 60ft needs some help. Possible go from the 225 to maybe a 245 or 255 if they'll fit. I would think you should be able to get 1.7s or so with that converter and gear. Maybe some adjustable rear shocks to help, but without a launch video it's hard to tell.
