more questions that you may have. Also I went from the stock T-45 with the stock 3.27's to the T-56 with 4.30's and my speedo wound up being a hair fast at 60(indicated 60 is about 54-55 actual) I bought a speedcal from brothers performance to correct that.
I love the setup for playing on the street but you better have plenty of sticky tire if you want it to hook in first, second, or third(at least for me anyhow- I am Kenne Bell supercharged) When I first went to this setup I had 315/35/17 BFG Comp T/A ZR's on 17 X 11's and it was pretty scary in the lower gears and then I went to 315/35/17 Nitto Drags on 17 X 10.5's. They still will not hook in first but second is usually good to go. Most of the time if I am launching on the street I do it in second gear at about 3400-3500 rpm's and it will spin about 15-20 ft and hook. I will probably drop back to 15" wheels and go with MT ET streets in the future to be able to hook it up unless someone can point me to a set of 17" or 18" tires that will hook me up. If your worried about rpm's with the low gears don't be at 60 mph in 6th I am only taching about 1600 rpm's(gotta love the overdrives) I am not really for sure of the gear ratio's between the Viper and Ford units but they are probably similar. I would not be afraid to go as high as 5.13's if they would fit and still drive it on the street.djtech said:How do you like the setup w/ 4.30's? I've got a T56 from a 03 Cobra and am going to do a gear swap (with friends help) in a couple months. I was planning on going 4.56's (if they fit).

...the speed sensor cannot be calibrated for a 98 because the 03 sensor sends a digital signal and the 98 ecm uses an analog signal? i have seen many people do this swap so i figured they dont know what they are talking about...
