It's nice to try and improve the performance of your car with simple fixes just to see if it works or not.I know todays traction aids are way better then what we had years ago and in fact i'm still running a snubber on my and i have no reason to spend the big $ for Cal Tracs when the car works just fine.
Here's a vid of my car with a fresh 408 in the beginning of last year.It was opening day and the traction was almost non existant.

I think my 60' that day was 1.50
I run a 9X30 slick with 4.30 gears
Have fun with what you're doing!
