I just picked up an 83 K5 with 305/350/208 and for a 305 it runs great. it has a 10 bolt front and 12 bolt rear with 3.73. It's got a good 4 inch lift with 35's. The body and interior is not really nice but it's complete and more than fine for a wheeling rig. Now for the question, I am not sure what I want to do with this truck, I will be wheeling it pretty hard but at the same time I want to keep it street legal. I am thinking of pulling out the carpet, painting it myself, I would like to paint the whole truck with the sand camo color and black wheels. I already have a 14 bolt FF with 3.73's that I need to clean up, shave, lincoln lock and install, since I'm a cheapo I will just run 8 lugs in the back and carry 2 spares. Any other good ideas, what would you do with it?
