Thanks, but I don't really want to know what ratio I have. I want to see what others have done as far as making the truck more driveable on the highway. I know with my current setup 65-70mph on the highway for extended periods puts strain on the engine. I know some guys install newer 5 spd transmissions, or regear the rear to higher gears or both. I kind of want to keep my 230/4pd stock setup and just work with higher gears. My question is, how high can you go without losing too much power on a 4spd granny gear tranny?
