Hi all

DeuceCoupe, thanks for your comments. I will look at the lifters. I actually was going to look at it today, but as I was opening the side cover oil began to leak so I tightened the bolts again, I need to drain some oil first I think.

Right now my big concern is the low vacuum reading. Will look at the weber once I can figure out the vacuum issue.

I did further testing today and disconnected and blocked off all ports and still the reading was the same. Now I know that its not my vacuum lines or whatever it is connected to.

What Vacuum readings do you get on the stock 250 L6? I was thinking perhaps this motor has a lower reading....maybe wishful thinking.
My vacuum gauge is steady so I cannot determine what could be the problem, like if the needle was bouncing about.

Thanks again for the advice.
