Tech II: I suppose that I should have worded that differently, I should have said I believe that the chain and gears are ok. I have "felt" quite a few that were shot and this engines valve train timing seems fine.
We would usually pull a valve cover and watch pushrod movement to verify a bad timing chain and gears. Just for the ease of it compared to the front cover.

I think that this engine has fixed itself, by that I mean I am gonna chalk this up to bad fuel. I took it back to the owner and I will be damned if by the time I got there the stumble was nearly non-existent. I am awaiting feedback from the owner but I think the Techroline and fresh fuel has fixed the problem. So I thank all of you for your time pondering this. I will try and help some one in return.
