Success! The truck started right up and oil pressure is great. Cam break-in wasn't quite a scary as I thought it would be. Still needs some fine tuning, but I'm happy.

I do have another question. I have oil coming out of a small hole in front of the downdraft tube. I'll start a new post for this issue.
Thanks again for all your help.
