What gears?

I know it may sound like a stupid question, but, I have no idea what gears I have in my truck. Its an '84 300, 4spd with granny, 4x4 with a NP208 T-case, 8.8" rear end. Anyone have a good guesstimate as to what I might have back there? Also, i am running 33" BFG's, would it be cost effective to change the gears? I can start in second no problem, and does ok on the highway, but the engine is screamin if i keep up with people on the highway. Doing a rebuild right now, bored .30 over, Holley 4160 550cfm carb (I know...too big...but, thats what I got, and has been on there for awhile), straight pipes with glass pack, no emissions (TRUCK tags), Duraspark II swap, and Crane truck cam. Any recomendations as far as gearing? Thanks!
Eric

Pull the diff cover and get the numbers off the side of the ring gear. If you can fit them maybe go up to 34" or 35" tires to lower rpms on the highway.
