8.8 rearend?

Ok, so I've been doing some reading and I saw somewhere that in 1986 Ford went from a 7.5 rear end to a 8.8 rear end in the LX. Is this true for the 4 CYL LX as well? Can I pull the rear end out of my 86 4CYL LX and get it re tuned to run with a V8?

you have an 84 4 cylinder? You will want to find a 5.0 mustang in a junk yard or something and get a rear end, tranny and drive shaft from one of those. that's what i'd do

I'd worry about getting a v8 in there first. I've seen people with 7.5's that hold up fine behind a stock 5.0 with decent care for a while they saved up.

This car isn't even going to hit the road till the drivetrain/suspension is complete. And I'm not in any hurry. Right now I am putting together a list of resources, gathering books/tools, redoing the interior at the moment. Summer is going to see the real work start.

I have no problem spending 5000+ on an engine, Im not gonna cheap out on the rear end. The catch is I want to do as much of the work on it myself as humanly possible. And so far ive never done more than change and alternator, or starter. Ive done brakes/shocks struts as well. But for the moment gearing tranny and engine internals I am clueless.

I have 31 spline axles, wish I had done c clip eliminators but oh well, and a rebuilt track loc unit from a truck just used the 03 cobra rebuild kit for cluthes and packed them tighter.

has held up great and have done this on other cars and had great luck and come out under 1000 dollars for a total rear end.

rebuild kit was around 110

truck unit 30 bucks from a junk yard

whole axle assembly 65 bucks from junk yard

axles 250 shipped from summit

Just a truck
5.4 3v: 264hp 317ft lbs rock stock

piecing together the next project

I have an 86 4cyl and an 84 3.8L V6. The 84 is the one in great shape that I will be restoring. Picked them both up for 250. Both run, I even manage to register and insure the 4cyl for the road with no trouble at all.
