Living with 3.91's

It's all about tradeoffs. Personally, 3.91/4.10 gears are my choice for old-school hotrods. I've run 2.73 - 4.88's on the street, depending on the engine and what I wanted at the time. Overdrive transmissions have made a running a deep gear much more bearable, if you can afford the conversion cost. Of course, I'm partial to a stout engine making noise at 3K rpm going down the road!
