I'm an owner of a 71 Nova with a 454 engine that I have just finished putting over 8 grand into. I've had it dynoed recently with an engine dyno rather than a rear wheel dyno and it came out with numbers I liked. I have one question about the gear ratio. If I'm going to put on mickey thompson sportsman tires (31X18.50) on a 35 spline axel. I was told I need a gear ratio in the low 5's. I myself was thinking maybe 5.29, but I want a few more opinions before I do this.
