Thanks 240z72 yeah that whole smog thing was a big part of why I had to get rid of my 77. It wasn't running right and I didn't have the money to figure out what was wrong. Once the DMV fees started piling up, it wasn't worth it anymore.
Alainburan, yeah I've seen a few (old) posts online of people who were selling their cars for much less than they have into them. I figured if I could find something like that, it would save me some $ and time. Good point too about the level of swap. I figure even if I do get a higher mileage transplant, at least everything would be there to swap in another motor or rebuild the one that's there when it comes time. Anyone know how many miles those engines are usually good for?
