Should I upgrade my gears, or should I wait on it until I do the engine/FI install? If I do upgrade, what would be the best ratio to go with? Right now, I'm not racing at all, and my Mach is my DD. From all I've read, gas mileage isn't going to be screwed totally with an upgrade... I'm just wondering what the pros/cons will be with a tranny swap, and what I'd be looking at as far as the numbers go (RPM/Speedo ranges).

If you get the t-56 viper trans, you will need 4.56's!!! It has a real slow first gear.
