FWIW......

We never lost a Shubeck without there being a reason outside the lifter itself. Of course, I treated them like they were the finest crystal. And I was obsessed with valvetrain control and maintenance. Honestly, if I could get someone worth a damn to make them, I'd use them.

We did have a rather ugly incident with PPPC, and I refuse to use their products. A member here had an engine utterly destroyed, was intentionally deceived, and seriously mistreated.

I have used and sold Trend for over a decade, zero failures, zero complaints. Well, other than price and delivery delays.

I won't use DLC coated lifters. And they won't work with cast cam cores, or certain oils. Talk to the people who make and apply the coatings, not the people who sell parts.

The cam companies don't want to make flat tappet cams anymore. CWC really does not want to cast cores, because there's no volume. Steel cores and flat tappets are an entirely different deal, and require different practices. The sole reason you were able to buy cast core cams is because the OE's and some parts suppliers were buying 10,000 at a time, 2-3 times a year.

There are a ton of terrible flat tappets out there, and an extremely limited number of high quality flat tappets.

Johnson HiLyft makes some really nice stuff, they have some lifters that are 60+ Rockwell C, ground, not polished to an exceptional finish, and they're available with the EDM oil hole done BEFORE the finish grind is done on the face.

People are careless with lifter bore location and size. It causes flat and roller lifter failures.

People think that they're chemical engineers, and they're going to make their own race oil. They're killing their engines.

Converting everyone to roller lifters will require a massive number of entirely new lobe designs. The vast majority of cam companies don't even have a lobe designer anymore, they don't want one, and they don't want to design a lobe, or ten, for you, the three cam a decade customer.

It's not a simple rule change. And if you let that genie out of that bottle, you'll never get it back in. And the genie won't care what it destroys.
