Interesting thread!
I didn't know a stock 1950's 235 cam now needed such rigorous attention beyond the initial special assembly lubricant.
The "break-in" attention that I have seen from original literature focus's 99% more on getting the new rings broken in.
I am from Missouri, could someone show me?
Anyone got a source from Chevrolet {1930'-40'1950's ---Shop Manuals, Tech Service Bulletins, Chevrolet Service News others }on the change in the cam/tappett priority over the piston rings?
I am honestly getting confused on the 235 break-in that I will soon be doing on my 51' (I have my old lifters and cam on the bench in front of me and I am wondering what the last re-builder did right. or wrong).
