Bob I am sure you will find that the MSD and Racepak will be your best friend LOL. Mike and myself have relied heavily on both. I still have the 7530 box in the car. In your case the power will not be the problem, but being able to manage it on the small tires. We run a 3.07 first in the Liberty and a 4.10 rear gear with 28x10.5 tires.
