they dont make it anymore....wtf. I doubt you could even find oil that is oil or afford it if you can, they are almost all synthetic or a blend now that you find at a local store
The EPA changed the oils starting with Clinton and it has just gotten worse taking all the lubricants out of it. THe break in was to harden the cam lobe and lifter. They would breakin to each other before they would harden and that made them specific to their location. It was cheap and easy to produce. THe GOV changed the oil characteristics so the engine manufacturers had to go to rollers. They didnt do it for performance, they had to do it to keep the cost low. Im sure the bean counters determined it was cheaper to go that route vs paying a union worker to breakin every motor with an expensive oil , then replace the oil. Its time consuming and would slow the production lines immensely.
As I said earlier overhead cams are a different thing vs pushrod motors. I havent had one issue with a flat tappet motor and am still using them because of the cost of the roller cams and the issues with those. WHen you loose a roller cam because the bearings let go its catastrophic and abrupt where the flat tappet is usually slower but both need the same parts replaced. Again the costs is thousands more for the replacement of the cam and lifters if you arent brave enough ( or stupid enough) to reuse those other surviving rollers. Bushed rollers add more cost and is what the professionals are using now.
Luck would be your area of expertise. This is the real world we live in...carry on with your fantasies. You have nothing to counter with simply because you have done nothing.
For the ZDDP worshipers...more ppm of ZDDP does not provide greater protection, it merely takes longer to deplete it. Real rocket science at work.

Good luck there pal....oh and i dont have a fantasy of having every car manufacturer and every oil company as well as the cam manufacturers saying The same thing as i quoted. But you keep on the good fight. So if you are a real racer, do you trailer your car or drive it to your races? And do your sponsers give you enough sponsorship money to rebuild your engine after every weekend or do you tear down and inspect or changeout the motor after each run like a professional does?
Exactly what I surmised...you have no clue. First hint...NHRA Stock Eliminator. Don't bother with the racing banter...easy to see you have less grasp on the subject than even oil.
So, you are taking your cues from :
Car manufacturer's - The same ones that tell you what oil they recommend? The same ones that recommend 10K to 20K oil change intervals? The same ones that advocate 0W oils for no mechanical reason?
Oil companies - I don't believe I have ever heard one say "our oil is not as good as the competitor's". Lots of hype and fanfare with no substantiation. These guys are the ones to listen to? Oh, it's got a symbol on the bottle saying it has been tested to "industry standards"...real informative.
Cam manufacturer's - Please...actual oil experts.
Ever consider outside the industry oil tests? Probably not. Can't bring yourself to read a simple blog? Here is a more technical reading... https://www.sciencedirect.com/scienc...01679X19303214
Like many here, you already know all you need to know...right?

Nice bit of information, HOWEVER, since just about ALL of the aftermarket cam producers recommend using a break-in oil with HIGH LEVELS of ZDDP, when installing one of their camshafts, I think that I'd follow THEIR recommendations.

Even after many of those so called "break-in oils" have been shown to be less effective than the standard fare? Using a correct oil negates the need for flooding with ZDDP.
Is it your contention that any oil with high ZDDP will work just fine? Based on what information? Btw, some of the "cam companies" break-in oils were the poorest performing oils to date.

You are free to believe whatever you choose to. All of what the rest of us are going on, is 60-70 years of personal experience with cars that have had flat tappet cams, and motor oils with higher levels of ZDDP...........

As are you...just trying to figure out the thought process on oil choices. The 327 depicted above backs up my views.

You just cant help some people.....cam companies tell you what they want you to use and give you a procedure, the oil companies make oil specific for flat tappets, even all the magazines tell you what is up with the oil situation and how to break in a cam for the best possible results and this guy still cant get out of the 70's.
Yet this guy runs the most modern synthetic oil in his flat tappet engines...who is it here that can't get out of the 70's? This is what happens you gulp down the marketing ploys instead of relying on science. I have already linked above about the additive ZDDP. More ppm of ZDDP in oil does not equate to greater protection...that is not how ZDDP works at all. More ppm only means it takes a longer period of time before it is depleted.
