Apparently I suck at drag racing...

8-1/4?
i don't thing so, maybe??
If you have a 7-1/4, you will brake it easy, with a set of slicks!
Rear end upgrade is first. If it is a 8-1/4 or 8-3/4 rear then you will be just fine.
Does a 7-1/4 even have a pad to bolt on a pinion snubber?

Any ways all Three of them items will help with hook for sure. Make sure you know which SS Spring goes on the right side.
