How to make Horsepower?

Do you have a 2 barrel carb ? are you running stock exhaust size ? what spark plugs are you running ? All these things can help more then most people know, me, Turbo is out of my price bracket.. I removed the heavy H.P robbing fan also. a lot of the small things will add up, fresh u-joints to wheel bearing and so on that can drag your Duster down.
