Ford 9 ?

V6 wagons & El Caminos were to have 2.73 standard in '79.

Unfortunately I have a 2.41

If you are planning to mostly drive the car on the road why would you go with the rear gear ratio of 350 with a 3 speed transmission. At 65 mph you'll be a little over 2800 rpm with a 27" tire

Very nice. What options do you have for conversion trailing arms?

In all sincerity, what ratio would you advise?

I would go with a 3.08

I would go with a 3.08

Or a taller tire if you're into that sort of thing.

I recently bought 245/45X17s. So thats a mute point.

A nice thing with a 9" it's easy to change the 3rd member. You could have one for street and another for the track. We had 4 of them for the race car set up for different circle tracks

3.25s are common and right in the middle. I run 3.00 in mine with mucho torque.
I’d buy a worm gear style LSD instead of Traction Lock as its design pretty much sucks compared to everything else.
