1977 scout 2

thanks for the posts it has some old 35s (super swampers) on it that dont hold air longer than a day so i ordered some mickey thompsom baja claws for it today. well the plans for it are: i have a 440 sittin around the shop that i was goin to put in my demon but with the amount of money i have saved up it wont even be close to bein done so im goin to put it in the scout. im not sure on what i should do suspension wise i was thinkin 3 inch body with a 4inch suspension not sure im new to the 4x4 thing so any help one that subject would be nice
thanks
