In the end, what the problem turned out to be was a mix up in the cam I got sent. It was a Marine cam for a boat engine which turns in the exact opposite direction to an automotive engine.
Like I said, could be a long shot, but if nothing else works, take another cam, stuff it in, and try it.
It sounds like a timing problem, my old man would probably say , lift the distributer, turn it 180 degrees, drop it back in and crank it over. It'll either start, or back fire.
The cam I have is an automotive cam. Got it at my local machine shop. Hmmm I kept the box will double check. If it is 180 degrees off would it still sound like it wants to start?
Got off work late today, will check on above suggestions tomorrow. But keep the suggestions coming.
