Anyone know of any SBM rebuild videos?

Well... Now I'm a little torn on what to do engine wise... I'm considering a couple options here now... 1) rebuild my 318 myself and just to have it machined. I was quoted about 1200 for a total rebuild on the motor by a machine shop. So in all honesty, I don't know if I would really be saving anything by rebuilding it myself.
2) find a 318 at a junkyard, or maybe even a 360, and just put that in the car, the issue with that is how do I know if I got good motor or a dud
