Re: 90 xlt 351 e4od stock, what 6\" lift & tires?
Try the search for this common question. Fill out your bio! This said here's my opinion.
I like my new goodyear MTR's. They are perhaps somewhere in between a full on mud tire and and AT. Priced good through Discount Tire.
There are post/sites on doing a shackel flip that is an inexpensive way to get the rear up or go with new springs. Perhaps not good for towing. Blocks are fine only for the street.
The front is complicated by IFS. You have to use drop down brackets for the axel pivot points, drop down brackets for the radius arms or new extended radius arms, springs, shocks, extended brake lines, and drop down steering arm.
If I had it to do over I would have done a SAS Dana 44 with leaf springs in the front and the shackel flip in the back. It would have cost less and I wouldn't have spent so much time with front IFS. This assumes I did the part hunting and labor, which I did for my lift anyway.
Look at 4wheelparts.com they have several lift kits for Ford IFS.
If you run larger tires, you also need to change your gearing 411 or better. I'd suggest 456 with that overdrive you have.
Lift + big Tires - gearing = not enough torque [img]images/graemlins/crybaby.gif[/img]
I'm running 37X15 MTR's with a six inch spring lift and some fender trimming. If I break I got an extra yoke, axels, hubs, and u joints. If I break again I go solid.
