Ok you masters of Mustangs, I have a friend that just bought a 99 GT, 5 speed and is making a drag/street car out of it, he has an extra rearend laying around his garage, and was thinking of putting 4.30s or a 4.56 gear in it, would these ratios be too much for a gt, I dont think highway cruising would be too bad with the overdrive, he doesnt drive it much on the highway anyway, but he was curious if anyone else had run a gear like these on a gt, would it match the power characteristics of the 4.6L? I'm not even sure of the power band or rev limit of these engines. We are all new to the modulars at one time or another
Thanks again
This car with mostly be a drag car, hes got a stockpile of parts that hes gonna use on this car, he just wants to be able to take it to the track or drive around town in it and just needs to know a good ratio to use, he will have slicks on the car
