Gears

Hey My 68 has the 2.79 rear gear and I was wondering if putting in a 3.00 or 3.25 gear would put a lot of strain on the engine while I was on the interstate???? Would it be better to just leave the 2.79 gear and put the money into a locking differntial??? Thanks

RE: Gears

3.25 would liven it up on the street without much highway penalty. 3.00 would not be noticable...

RE: Gears

You can run lower gears with an AOD and still have decent gas mileage with no more strain on your engine. You engine should be able to handle lower gears anyway.

RE: Gears

Hey thanks for the replys....an aod is out of my price range for now. I'm pretty well set on 3.25's then.

RE: Gears

Just an FYI, if your going to go through all that work, go with a set of 3:55's. I just did mine and its fine on the highway as long as you keep it at 55 - 65 you're good.

Ok, Im sorry, but 55-65 on the highway is grandma speeds. IT'S A MUSTANG. I wouldn't do anything to it, that would cause that. I like to cruise the highway around 75-85.
