Any 2500 lb car with over 500 hp is going to have traction problems no matter what ratio they have. You just have to match the rearend to the rest of the drivetrain.

I had a 3.70 gear in my Cobra, behind a 530hp 428 FE and a TKO. The 428 was cammy, with the horsepower peaking at 6500. The deeper gear worked well in this situation, but you still had to have some sense and know that you couldn't go to WOT in 1st/2nd gear.

With a regular 5 speed, you can even use a deeper gear to your advantage with a larger cam. An engine with a fussy powerband coupled with a high rear gear a .64 OD is going to keep you bucking along at cruising speeds.

A radical gear change is the cheapest way of increasing the seat of the pants excitement. I do my own work, so $150 for a set of gears and $50 worth of bearings is great fun when you're going from a 3.08 to a 4.10. LOL
