Once the 60s are in you should be able to get down to a 2.8 pulley on E85, that would be the exact same mods as my car. In for results with my car on the set of pregens and drag radials on them im pretty confident it would crack 12s. So I'd like to see how your does.

Edit I have a good trans and the TEP VB makes a huge difference, along with the 7/8s chain setup. Ive destroyed 2 flexplates in 6 months so I honestly don't see your trans lasting very long.......... Good Luck!
