The 3.73's are finally in. It was un-nerving at first. For some reason the splines on the pinion gear was not cut correctly. (Ford Gears) The mechanic had a hell of a time getting it to work. The rebuild kit I purchased was Richmond and didn't have the right spacers wich made it a waste of money according to the mechanic.
Anyhow, they are in. I notice a difference but not to the degree I thought I would. I went from 3.27 to 3.73.

I think that frame stiffening and traction bars are next as I have mentioned. I feel that to make the car go any faster will require much more money. As I have said, it is a daily driver too. I am trying to be realistic too. Still not sure about under drive yet. Too much to worry about.

Some people mentioned that the 70mm TB is to large. Should I go back to the stock ? To retain the 70mm TB do I need to change heads with the intake or can I just add a new intake? Can I install it myself? I know I can't do heads but I feel I could do an intake.

Peace and strength friends.
