I have 4.10's in the rear of the car. I might just pull them out and put them in the truck. My mustang setup was full bolt ons- comp cam ***** Thumpr camshafts, eagle crankshaft, under drive pullies, it was dyno tuned, and a couple other small things.

You would have to put 4.10's in the front as well.

What size tires are on the truck? With 6,500rpm 4.56's would be a beast.
