I had an 81 short bed with a 302 and a C6, best truck I ever owned. Unfortunately I couldnt fit my kids and wife in a regular cab and had to sell. I ran 2" Daystar spring spacers in the front and add a leafs in the rear and a 2" body lift and cleared 35's no problem. Before I did the spacers and leafs, I had only the 2" body lift and ran 33's with ease. Stock height 32's will fit as well however you may run into issues with the tires rubbing on the trailing arms but its not a big deal. I had a slipper in the front diff and a Detroit Locker in the rear and that truck went places never intended for a full size truck to go. Great trucks, great pick..
