I would say it depends on several things. Weight of the car, type of 5 speed, purpose of the car(street or strip), what rpm you shift at,..etc...

My old DSS 331 (10.5:1, AFM N-91 cam, AFM stage 3 TW'S, parker funnel web,AED 850ho carb,etc...)ran great on the street and strip with 4.56's and a tko 500 tranny. I would shift the car between 6,800 and 7,400 rpms.

Guess it's all in what you want your car to do. It's hard to make a gear suggestion without knowing more about your car.

Honestly I would leave the 4.10's in the car with that setup.

I should have asked this earlier but why are you contemplating changing the gears? Are you after fuel mileage, less tire spin...etc..?

wanna be able to drive on road and strip and yea less tire spin kind of

With 4.10's and a t5 or tko you should be able to run 60mph and only be taching around 2,300-2,400 rpm's depending on your rear tire size. That's not much rpms so I would leave the 4.10's in the car.
