what is a good axle gear ratio

I have a 66 c10 with a 327 engine with a 3 speed. need to change the rear axle gears so i can keep up on the highway. I have 4:56 gears and run 60-65 max, any faster I will blow up the engine. What is a good all around gear ratio to run 70 comfortably but not totally lose my pull from starts?
