Squeeze and Yar -
Thanks for your replies. As it sits, the engine runs and runs very well, so I'm not inclined to tear it apart until I have to. I tried to ID the engine because at first glance it appeared as if it might have been the original engine, which would have been nice, but after looking up the numbers stamped on the pad on the pass side, I can say with almost absolute certainty that it is not. Not a big deal at this point, but at some point, I want to ID it if I can.
I don't know how accurate the numbers are that are stamped on the pad, but they ID'd the engine as an 1970 4bbl 350 that was used in a Caprice/Bel Air/Kingswood station wagon with a turbo 350 transmission.
Maybe I should put some fake wood panelling on the side of the bed to make things match
