Advice vs pros and cons of engine flush

You may be correct - but I’m pretty sure that the parts list for my engine rebuild included a cam. That would put approximately 60,000 miles on the cam. Would it wear down that quickly?
I hope not. But our 318 only had 30,000 miles on it. Of course it still ran good, just had an annoying tick when cold. Probably put another 30,000 miles on it when I felt safe to put a small cam, 4 barrel carb, and intake on it for my son's 73 Dart. If it runs good I would not hesitate to run it.
