Solid cam damage diagnosis help

Lil Demon said

Hmm I’ll be doing the taper measurements tomorrow. While I really loved the performance and character of the Hughes cam I used and built my entire setup around that grind, some of the comments are making me consider another manufacturer. What is the higher quality cam manufacturer for solid flat cams?

Howards grinds Hughes cams, on cores that Hughes has sent to them.

I’ll be stunned if the cam is ground wrong. It could be, but the guy running the grinder lost his mind or it was his first day on the grinder without supervision.

I do the same as PRH in that I put all my cams in between centers and make sure they have taper. Never seen one ground like PRH is saying, but I have no doubt he’s seen it, and I give him a good chance of being correct.

I also do every single lifter, every single time. There was a time when I’d stand at the lathe and spend hours going through 500 lifters at a time. IIRC the fail rate hit as high as 45%. They either had too little taper or the vast majority had a wedge cut on them.

That was the mid 2000’s and I still check them all.

The junk that makes it to market today is sickening.
