1979 f250 suggestions

I recently got a 1979 F250 that I am turning into a mud truck/off roading truck. Its got a 300 inline, 4 speed manual, and 4.10 gears. It will not be on the road at all because we have no title. We have taken it out a few times and found out that we definitely need some new tires and more ground clearance. I was wondering what is the best and more cheaper ways to lift this thing is? Also what type of tires and what size should be get? We are usually in mud, clay, and rocky or muddy trails. Thanks for any suggestions.  

i would suggest a custom 21" lift with 47" LTB's. i just happen to have everything you need for sale
