Well, I went to Littleton U Pull yesterday after work and I was pretty excited hoping I was going to find all the treasures I could dream of aaaaannnnnd, I struck out. And I might have gotten rained on a little bit too haha.
The C20 had a tool box bed on it and a rack for what looked like piping or something. The dude had an Edelbrock sticker and a couple of other performance stickers in the back window so I was hoping for a big block with some good shoot on it. It was already stripped of the intake manifold and what I am assuming was the headers, but it didn't matter because it was a small block any ways. As far as the smog pump hunt, the C20 didn't have one. I did find one on a C10 with a small block. I think I might have been able to make the pump work, but the bracket probably wouldn't have worked and the rest of the system would not have worked at all. So I will continue watching when they get stuff in and try again.
I did learn two things about becoming a junkyard dog though. 1) leave your tools in the truck until you find what you are looking for, and 2) check the weather before going to the junkyard!!!
