Depending if your engine is stock or not? If it's stock? I'd go no more than a 3.5. Even semi stock still 3.5.
Problem is diff gears will assist with a skid but if you don't know what your doing you can have 500hp at the wheels and still not do a skid.
Theres a technique which is:
Idle on the spot just creeping along,
Just apply the brakes very lightly. Just enough to stop you,
Keep your foot on the brake lightly,
Thump the throttle and you should have tyre smoke.
If you've applied the brake too hard? You'll look silly.
I used to be able to do it with a 3.0lsd, auto and a clapped out 351 that was running on 5 or 6cyls.
