Brent,
In the Words of an infamous--------, I feel your pain!!!
You have recieved a lot of good responses to your thread. Two things that bear intense scrutiny:
1. The cup adjusters as mentioned earlier!! If you can prime the engine; Take out the distributor and run a drill motor on the
oil pump drive, and check to see how much
oil is coming off the cup!!!
I didn't see how much
oil pressure you are running in this motor, but I like to see about 80 to 90 lbs and then I restrict the oil to the rockers depending on the requirement of the perticular engine. They all are a little different!! You should see a small oil line coming off the adjuster cup if everything is correct. The rocker design incorporates an oil galley through the rocker down the adjuster to the cup. Make sure this is functioning correctly!!
2. Cam bearings can diffenetly be the problem too. I can't tell you how many motors that I have torn down when they come in for a build, that have the cam bearing installed improperly. Also, there are two grades of cam bearings available. Fed Mog has come out with a race cam bearing that is harder that the stock replacement so that you can run more spring pressure. I use the Durabond hardened bearings in my motors. As previously mentioned, the oil galley runs underneath the cam bearings, so you are getting less support under the bearing than in other motors!!
If you give me a call, I can run you through some tests to try to check to see if its cam bearings, or the cup adjusters.
