OK, you've located TDC. So you know where the crank is....now you need to degree in the cam so you know where it is.
Ya Brian, I only know one way to do these cam deals, so difficult to relate to just sticking them in. I know it is common practice, but I'm not a fan of tearing engines back apart chasing issues, LOL. Besides if your looking to maximize performance it's just about a requirement.

I'm sure Russ thinks I sound like a broken record (and I could be dead wrong), but I find it difficult to attempt to troubleshoot a problem like this without 100% nailing down all the basics.
