True Bracket Car vs True Street Car....

A lot of these street and bracket cars have 8 3/4s. Get a good converter and you can run 3.23 or 3.55 during the week and swap to 4.56 or better for the strip. Did it a lot when I was younger. 9 1/2" converter in my 71 Demon, and then in the 4 door Valiant when we were expecting our third son. I never had any trouble with the converter with the higher gears.

I did eventually compromise and settled on 3.91s.
No more friday night gear swaps!

My oldest son has that valiant now.
