is gear to much

I used to run 13 x 31 slicks with a 4.88 gear in a 440 Super Bee. The large diameter tire will allow a pretty high numerical gear to be used but you`ll almost have to have a stout solid cam. With that said, when you get into the 5 to 1 ratios you`re usually talking high revving small block. The best way to find out is to take your combo out there and see what rpm you go through the traps.
