Re: Over-Drive vs Gear Change for a '34 Coupe

I've toured fairly extensively for decades in a '34 Eight sedan with the 4.69 rear axle. I've resisted either changing the rear axle ratio or adding overdrive; I like the lively around town performance it gives and great hill climbing with the 4.69; the downside is I have to behave myself and settle for 45-50 mph on highways. Assuming you're inclined to want faster highway speeds the choice will depend to some degree on what rear axle ratios you can get. With Phil Bray out of the scene, I don't know what's available in new gearsets. An original 4.07 set would be a nice choice. But IMO you'll get the most flexibility by retaining your 4.69 rear and installing an overdrive.
