After driving my '71 around for the past three years with it's TH700R4 and 3.08 gears I decided to treat myself to a set of 3.70's. I ordered them from Summit Racing and they should get here by Friday or Saturday. And I also ordered the speedometer gears needed to correct my speedometer.
With the 3.70's I'll be able to make full use of my lower three gears for 1/4 mile passes and still run only 2040 rpm at 60 mph in 4th. Can't wait to try them out.................
