Whats is worth 8 3/4 with suregrip, drum to drum, 3.91's

it ain't going to be running and driving along if you take that rear end out of it! Out of curiosity what's the new plan?
lol a 9inch with a locker or spool. going to a drag car only. I know the suregrip will live, but I want to pass it on to someone else before I start laying down 10's, and running it on the ragged edge.
