As long as you don't bump up the compression too much you will be fine with pump gas. Race fuel doesn't add any benifits to a low compression engine.

IMO I think it adds a little bit of pep to it. It also burns the carbon build-up out of the motor.

Key words there were in your opinion. You're entitled to one, everyone is. But facts are facts, and the bottom line is that race fuel does absolutely nothing for a low compression engine. If anything it will hurt performance cause it burns too slow under those conditions. Compression builds heat and race fuel is resistant to igniting and burning up from that heat untill it's actually sparked from the plug. Save the money you're wasting on race fuel and put it somewhere else.

UNI filter, no airbox lid porting/polish, carb (a bigger one, or simply rejetting for more fuel flow), and a cam. boring alone does not add much power. you can probably find a piston for your mojave that will let you run 91/93 octane without pinging. sprockets would help too, but would not add horsepower/torque.
