hey all, I'm looking into raising my highway speed a little without changing my driveline in my '69. what is the best gear ratio to go down the highway with the 305 v6 cruising comfortably at 70-5 mph but still have all the pulling power as before?

i believe I have a 4:11 gear ratio in it now, but all I can say is it's slow. it is at about 3000 rpm at 65 mph with the wind to my back.

Thanks in advance, Indy wink
