You should get a 4" lift with a 3" body lift. Then with a little cutting of the fenders you should be able to fit 33" tires. The main problem with s10's is the wheel wells are so small so you almost always have to cut the fenders to fit larger tires. Also you might want to swap in a solid axle in front. Independent suspension sucks. Hope that helps.
take off the body and put it on a full size blazer or 1 ton chevy frame, shortened of course. 14bolt and d60 front, 4" lift and your set to hit any trail. a lot of work though. look at white knights rig. it kicks some mean a**.
white knight good job with the swap. it looks wicked. a little to big for my likings, i'm a rockcrawler, but kick a**. good job.
