3.07 can work. Needs to be a V-8, preferably a 350 or larger. I drove my 67 Bel Air with a 283, TH350 lockup and 2.73 gear for 175,000 miles. I experimented for try for some fantastic MPG number. 20 MPG was all I got. If I were to do it over it would be a small block 400, TH350, maybe a 3.08 gear. screw the absolute MPG numbers. A heavy vehicle LIKE a pickup needs gearing to make things easier for the engine.

I'm not a proponent of O.D. transmissions. My 67 and 68 pickups will both have 3.73 gears when they get back on the road. I will compromise on the side of power the rest of my life. Needs to be at least a little fun to drive. My Bel Air ran great, just wasn't any kind of a powerhouse...
