You might want to do some research on your adversary, in terms of what the various magazines got for ET & MPH. Might be better to run a 1/4 rather than 1/8, Hemis have a strong top-end "charge". His car may have traction control. I think the new Mustangs require a rear brake change to fit 15" wheels & slicks, but big-rim drag radials are available, so see what he's got for tires. He may not be good at power-shifting (Tremec, IIRC). If you can hook, mid-11s should be pretty easy, but you should put a few laps on your car & know. May the Dudek-Force be with you!
