I'd purchase the car and set up a 6.0 for it. They're everywhere now, and with simple mods have enough torque in that size car to really surprise people. It's getting easier to find an aluminum block, too.
The rear end really isn't that much of an issue on a road course, it's the drag racers that blow them up most often.
A good friend did cam and heads on a 6.0 in a Silverado here locally and got a solid 100 hp on the dyno. That's a ton of gain for not much coin.
