Since a few years flat tappet failures have been going up. There are several factors involved (new aggressive lobes, oil formulation etc.) and one of them is the quality of the cam core. Which companies are still making flat tappet cam cores? Which cam grinder uses which company? Or do Comp Cams, Lunati, Bullet, Mike Jones all use the same cores?
Is there a reason why choosing one cam core over the other?

Thanks

For flat tappet cam cores that fit a traditional B/RB or 59* SB Mopar with std journals.......I'd be pretty surprised if there was more than one or two places supplying cores.

Engine Power or Camshaft Machine.

Thanks! I was told that there are different quality cores/different hardness for flat tappet cams (e.g. EP2, HC, P55 for Engine Power). Not sure if this information is still correct.

I assume they all come from China as they seem to go flat so fast.

It's correct for something like SBC...... Not a BB Mopar.

For flat tappet cores for that platform, i suspect there is probably only one core choice...... Maybe two(one wide lsa, one tight lsa).

Who was the "CW" that I used to see on my flat-tappet cams? Or am I confusing "CW" with "CM"?

Brad, I think it should read CWC (Campbell, Wyant, and Cannon Foundry - now known under CWC Textron) which is the foundry for the cores. They provide the cores for CMC and EPC.
According to the website they only produce two types of cores: ductile iron and alloyed gray iron. On CMCs webpage they only list one type (material) of core for Mopar BB flat tappet: Proferall (I assume it's Proferall ++). They have two different cores in terms of LSA/duration.
The same material is used for pretty much all flat tappet cams according to their catalog btw.

I have a new unused Engle Hyd Flat tappet cam I bought in 2002 for my 360. Is this camshaft old enough to be of the better quality metal then todays cams?
