I agree with the gear change reco. That was the first thing I thought when I read your post. The good news is gears are not expensive.
BTW, I wouldn't worry about the motor idling. None of the convertors are so tight as to prevent that. What will change are the RPMs to which the motor will "flash" when you stab the throttle.
Either way, that cam in a 302 and 2.79s are a bad combo...
