Thanks guys. It is a 1990 RC with a TBI 360/A518 tranny/NP241 transfer case. Lol, I have a 3" Tiger-built extended shackle (he has plenty more to sell if interested) in the front with sagging springs and a F-250 block in the rear with add-a-leaf. The tires are 325/60/15, which on paper, comes out to be 30.6x13/15. My truck has over 200,000 miles and still running strong. Smokes like a mother, but is funny when sitting in traffic. Those tires made a whole lot of difference in the look of my truck. My plans include a built 360 with an 871 blower, built 727, and I don't know which transfer case. I have a 360 sitting to build up. I plan on taking my old 360 and computer out and rebuilding it and putting it in a small car. I also think a roll pan would look nice and a tube bumper up front.
