3 Speed to a 4 Speed??
Alright guys, I recently bought a 67 Mustang Coup and restored it. It's ready to drive and sounds perfect, with ONE thing wrong that is more of a personal problem to me than a serious mechanical issue: it only has 3 gears, 1 reverse, 2 forward. I want this car to be able to do more than 55 MPH on the highway without the RPM's redlining so my question is:
Is it possible to add a 4th gear to the car? I spoke to a man who said it was possible but I would have to change the entire back end out. If not, are there any ideas to help increase the cars top speed? Any feedback would be appreciated. Thanks
