Thanks for the info Randy. I have heard from a pretty reputable source that the new SJ Rated oils have very little, if any zinc and other compounds needed to protect flat tappet camshafts. This is due to emmisions standards. EOS has plenty in it.
I personally have only had one cam go flat, but we think there is a problem with the block on that one ( 390 Ford) The cam was basically stock and it has wiped another lobe on the replacement.
I really wish the cam companies would chime in or publish some info on this, they have got to know there is a problem. One thing I absolutely do is to tell customers that are using a double spring to break the cam in with the outer springs only for at least a couple of hours running time.
Also, I do not like Comp's cam lube. I have been using the ARP Moly lube that they sell for thier bolts and studs. It stays where you put it until you start the engine.
