[Awesome 72]

After a big struggle.....Mark finally extracted and replaced the cam bearings,
He now says, because they are a tight fit, that it's not a good idea to put
a new cam in to run in the new motor parts. So he plans to put a prior one in to run it in. What do our Brother C3rs think.?

Mark and I talked about this- I feel it's a waste of time and energy to install an old cam & lifters, only to pull it out and replace it once the rings have seated. As long as you don't let it idle at 700 RPM it'll be fine. I usually run around 1500-2000 for 10 minutes, shut it off and recheck for leaks anyway, then go again. Worked for me for 30+ years.

Keep us all posted on progress..
