newly rebuilt and a knock

What is practical is contacting rebuilder, apprise him of problem and seek his advice!!

In the original post he said, "The rebuilder says it was fine when it left his place and i must of done something like maybe the timing was off."

Looks like he's already done that and the builder is telling him that the engine was fine when it left, making it the owner's problem.
 
If it was me... 1. call the rebuilder and talk it through, have him tell you what to do to troubleshoot etc. 2. People are busy, it may take some time for him to reconcentrate his efforts to helping you. 3. Document, Document, Document. Write down EXACTY what you did WITHOUT filtering it. Keep track of when you called the builder, what you said/he said. Also video is your friend, make a video showing engine oil, coolant in radiator, sound of engine etc. 4. Things happen, rather than try to figure out who's fault it is, try to partner up with the builder to resolve the issue.
I'm not finding fault with what you have done, your unwillingness to disclose the builder until you've worked through this says volumes about your integrity.
 
Here is another idea: Post a video of the knock on the Barn. Others have done that and their knock was able to be analyzed.
 
The distributor drive shaft was stuck in the drive end and the top end . This should not be a tight fit at both ends it acts a universal joint so is a semi loose fit . Repro shafts sometimes have to be dressed for the fit to be correct just a connection not a rigid join . When you pulled the distributor up as the shaft was jammed at both ends you were compressing the spring which holds the oilpump/distributor drive gear down in place . It could be you lifted it up so far that when you pushed it back in you engaged the drive gear out by a tooth on the camshaft . This would affect the timing the engine will run but it would not be happy maybe causing the knock . An easy fix use the timing pin for TDC and reset the cam as per the good books . I would pull the shaft out with needle nose pliers and dress each end for the correct fit you should not need to press it in position . When you pull the distributor out the shaft stays in the block .

I'm changing the front bearing on my generator, it was/is worn out and was causing some knocking.


Update: Well it wasn't that bearing...damn it

Listen to what the man says! He is s true expert! Wayne
 
If you have to push down on the distributor it sounds like the spring that holds the dist./oil pump drive gear up has popped out of position. That spring kind of wants sits at a cockeyed angle anyway and is easily installed so it can kick out. Remove the valve (side) cover and see if it's out of position. Also check to make sure it was installed correctly. It goes on top of the drive gear. I would not run the engine until you check this and fix it. If the drive gear is pushed up the oil pump probably is not operating and that's not good at all.
 
thank you all for your help the problem has been solved it was a timing knock. the lower distributor shaft was stuck in the cam gear coupler and also stuck into the bottom of the upper distributor shaft. got everything out of the motor clearanced the shaft so it was a slip fit put everything back together and now it is all set
