Default which is better fro the street, 3.73 or 4.10

automatic trans in a 98ss TCI 3000 stall converter. I want to know if I put 4.10 in what it will do for my car and what he negatives are, will my engine rev high going down the highway and also will my gas mileage go through the floor? Thanks

With an auto that sees a decent amount of street use I would go with the 3.73's. The 4.10's would work better in a manual. Not that 4.10's couldn't be used in an auto but the 3.73's will be better.

4.10 would suck on a highway for an auto. At 80 my tach is almost at 3000. Let me tell you, your exhaust his humming at that rpm

2900 RPMs? Now I don,t feel so bad about my 3000 RPMs at 60 with my TH400 and 3.73s. My gas mileage stills sucks though.
