Engine builders don't like flat tappet cams for ONE simple reason, there to much work! All that required break in procedure, who needs it. A hydraulic cam is much easier to break in (and STILL requires a good break in oil) and it's easier to warranty. So why would an egnine builder today want to be bothered with the hassle of breaking in a flat tappet? Simple answer, they don't!
So the easy solution is to bad mouth flat tappets and charge more for a roller. Talk about how you have to use special lubricants and the hassle of valve adjustment and the 50-50 chance you will "wipe the cam". It's a win win for the engine builder, more profit, less work, less worry.
All that bad mouthing is just like what is so often heard from the alignment shop. If you don't buy new shocks (from me) your going to crash and kill your whole family! Oh my, the paranoia runs deep, at the expense of the consumer and the profit of the builder.
Hydraulic's have their place, in Undy's car, I'm not afraid to run the real thing.
