is 4.10 too much????

Hey guys im building an 83 grand prix street/strip car and im going to be running a 400 small block with a th350 tranny and im deciding what gear ratios to go with. Would a 4.10 gear be too much for a auto 3 speed car with a 29" tall tire? would it be too much for a street car sometimes highway driven? Thanks.

I would think it's to much for the highway with a 1:1 tranny ratio.

yeah im just looking for some rough guesses, my goal is 11's w/ spray cam and some stock ported heads and what ever other bolt ons. but when i get a 12 bolt i dont know what gears to pick, 3.73's or 4.10's
so if i traping around there what would the 1/4 et be, understand or did i throw you off?
