Re: New cam break in
^^^^^^ I would definitely do this with today's products. In the time before china and recycled metal, hardly anyone did this and failure was low. Some builders didn't even follow the 2000 rpm for 20 minute rule. Do you think auto factories did this. We did run them all on propane for a short time checking pressures and listening for noise.
With today's flat tappet engines, proper break in is super critical.
