I want to do A gear swap stock is 3.27 and at 75 mph the tach is only at 1900 or 2000 would it be worth it to do 3.55 or just go 3.73 I do want more performance but do not want to run to high of rpm on the highway the transmmision 5th ratio is .63
In my opinion and the opinion of a lot of the other guys on here, 3.73's are probably the best street car gear there is. 4.10's will perform a bit better at the track, but the penalty in gas mileage will be a lot more significant. Since your stock gears are 3.27's, you probably wouldn't notice much difference if you went to 3.55 gears.
