7.something sounds about right to me too. No way they would have 3.50 gears in a big truck back then. How about some HEMTT 16.00X20's? A tall tire would lower the engine speed, but at 95hp, it isn't going to work. If you go to a truck wreckin yard, and get a brownie box, it may help. Some guys stick em in backwards, and get a 200% overdrive. Why such a low hp rating? Get it at a good price?
