1985 GMC 4x4 LS Motor Swap, tons of pics!

Here is my current project I would like to share with you. I bought this truck in July 2011.
The short story: I was pulling parts off a part-out Mustang for my Foxbody when I saw this truck sitting across the lot. I said to the man selling me the Mustang parts that I liked that truck. He said it's for sale for $1800 as it sits, or $3000 after they figure out what is wrong with it and fix it. I told him I'll take it as is, non-running and snapped a picture of it:


I had a friend tow it home for me. The truck is an 85 but it has a 350 TBI motor out of an 87 Blazer and the rest of the drivetrain is out of a 91 as well as the single front accessory belt. I put gas straight into the throttle body and the truck started and ran fine until I stopped pouring gas down it's throat. So it was a gas problem. Simple.

I pulled the bed off.


I also pulled out the gas tanks. Both were rusted through, but that wasn't the no gas problem.
