So, are these lobes that Bob generated out of a computer program or are they Cam Motions lobes that were picked from a catalog? I also have the question in the back of my mind... Is somebody sourcing over seas cores and selling $500 custom cams on junk cores? Having bought a few cams from Bob and worked on customers engines that had MK cams installed previously before I was involved. I've noticed that some of the cams have MK stamped on the nose of the cam and some do not. Are the ones with the MK stamped the magical cams? And the ones not stamped Cam Motion lobes?

I believe once you had issues, it went from Haxby is the best, the guy is so awesome, to , haxby is a liar, haxby is not running enough valve spring, haxby sucks.
We already know I'm a gravel hauling troublemaker, who googles stuff, never turned a wrench, and is a liar.
Dam he is good at damage control.

You must be talking about these. Besides the wear issues, they weren't making the power. Swapping them out with different cams, one from lunati, other ones were howards, the power went up, as you already know this story. I believe that was when bob starting telling everyone, MER doesn't know how to tune a holley EFI, MER 's dyno is way off, MER sucks, and so on.

I wouldn't blame the issues on CM, they are doing what the customer wants ie BM . Comp and Dyno Cams ground us some crazy **** over the years and would always say ..... Your on Your Own with that design guys. They know what works . The Cams in MTs picture look to have lifter perpendicularity issue or the Grinding Wheel on the cam grinder was loaded up , or improperly dressed for squareness , It almost appears that it was ground tapered like a solid lifter cam to make the lifter rotate!

Marine Kinetics Bobbby is an excellent snake oil salesman with a good amount of conman built in.
Great at never putting anything down in writing to bite him in the ass later.
Feel bad for Orlandi Performance, Brian was severely bamboozed to the point old Butt Hurt Bobby was pulling the strings behind the scenes and Brian was making phone calls to peoples work getting them in trouble, not to mention getting kicked out of here over it. ( mods should reconsider letting him back in imop)
I am however enjoying being able to speak out about BHB without having to wear 3 sets of flame suits around here finally.. he has cost many people a lot of $$ and pain and suffering.

What that guy said. I've been saying the same thing for years now. I had avoided pointing out that Bob has literally zero hands on practicle experience in this field, because all his cheerleaders turn it into a chit show. After sharing info with other builders on this exact subject regarding his cam "designs" which led them to see past Bob's bs and realize what was happening, Bob began a smear campaign behind the scenes attempting to discredit me. That is why I started the cam thread earlier in the year. Unfortunately, instead of it being a learning experience, Bob's cheerleaders tried to distract from the facts. It doesn't matter what spring pressure, or how thick a pushrod you use, if the lobe isn't stable it's gonna wreck stuff. Also, when you grind through the heat treat on these cores to get your magic profile that you learned about in a seminar and tested on your laptop, its gonna look like tims. Send the core to Callies, that's who makes them. And the can test it. But I'll dave you the time and tell you it's probably been ground through the heat treat, like many others. I'm not trying to sell cams, or be the man. Just trying to save people hard earned money and time. I'm sure many of you will be receiving phone call from the con man today. Ever wonder why he won't post in public? It's much easier to lie on the phone and not get called out
I've been a Bob cheerleader for a long time, but today that ends. If you make a mistake own up to it! With that said- I'll own up to my mistake of listening to Bob and not others on here trying to give advise. Then telling them they don't know what they are talking about, BUT being told by Bob to not repeat what I was told- or say it was he that told me. Whatever live and learn!
