Sounds like a good time for you and your father. He’s also probably familiar with the process to break in a hydraulic camshaft. If not, there’s lots of information on this forum about doing that process. Be sure to check that the lifters rotate in their bores as the engine is turning over. That’s a big part of the problem with the cam failures that people don’t check. I never did until it was pointed out here. Keep us informed of your progress.
