I think it depends on your engine. I have a '51 coupe with a straight transmission (no overdrive) and 3.55's. I have a pretty stout Mercury engine in it, and everything is fine with it, except that I keep wanting to "grab that extra gear" on the highway. I was thinking about picking up a 4.11 "chunk", but decided that I will stay with the 3.55's for the time being.

I'm not going to win any drag races anyway, and I think I'll be able to pull them at anything over 60. (Things are also pretty flat up here in north central Minnesota.)

EDIT : I forgot to mention that I am putting an OD transmission in the car this summer.
