Hello everyone I have a hopefully simple question. I just picked up a 96 cobra a few months ago, it’s all stock except from what the calculators say is a 3.73 gear ratio, ( though the original 3.27 tag is still on the axle, and doesn’t look to me like it’s even been opened up). My question is, I’m looking into Getting some 4.30s, but from what I can tell my only option to correct the speedo is the Dallas mustang speedcal that is no longer made. Is there a tuner I could buy to correct the speedometer for the swap. I don’t want to go to 4.10s just to throw a short lived plastic gear into it to get it almost correct. These 3.73s just don’t pull in 3rd. , and I want to get the acceleration from this 4v like my Mach 1 had. Thanks for any help

I keep seeing conflicting info on the turner, some say it will work an others say it won’t on a pre 99 car.

94-98 cars are VSS so the speedo signal goes straight from the sensor to the cluster so you need a speedcal. Get one secondhand. 69galaxie already has you hooked up, just get it from him.
