There are large parking lots by my house, I went in there and just played around to see what kinda manuverablility the car had. I'd suggest something similar to you. Mine's a 71 Chally R/T with 383 auto.

Practice this in dry and rainy weather in empty parking lots away from light poles, when I was young I used to take my 71 Duster to places like this in the rain and practice doing controlled doughnuts, figure eights, and if there was an island in the parking lot, I'd practice sliding around that in each direction.
At the time this was just some youthful clowning around, but because of the practice and knowing what my car was going to do, it saved me more that a few times in my day to day driving.
