340 break in question

Roller cams have much less friction on the lobes than a flat tappet cam...

Break in is critical with a flat tappet cam as the lifter and cam interface is under shear load... There is no boundary layer lubrication on the cam and lifters like there is with the crank and rod bearings.... The sides of the lifters have pressurized oil, the bottom of the lifter and lobes of the cam are just splash oil...

You keep revving your engine cold, I will wait until mine warms up...
I understand how oiling works. Just to be clear, your argument goes against not only my opinion and many others, but also just about everything you could ever find to read on the subject of engine break in. Once my engines have oil pressure they get RPM, for break in.
