I've been reading about this issue from Tim, and you over the past year. What really bothers me is Bob never chimed in once! A few years ago I was having Joe run some numbers for me. Then I get a phone call, saying I'm getting really bad advise followed by a dozen technical reason why the combo I was going to run would suck! I ended up getting into a year long chit storm of arguments with, Joe, Mike, Kevin and Dan. Never once did Bob jump in and say what I was saying was correct. Maybe because it wasn't correct. A little over a year ago I was buying some stuff from a guy with a Nor Tech up by Fox Lake. Guy said he installed a MK cam and lost 5 mph vs the 651 that was in prior. Like all of you are saying here, Bob had every excuse under the sun as to what he (boat owner) did wrong and that the cam was not the issue.
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!

We should be helping each other out, to avoid issues here, and in person, as thats what boaters used to do. Bob did a good job of dividing everyone up. You were either with him, or you weren't. Either way, glad to see your post.
I think soon, the oso tech section, will be great again.

that No-tech owner reground the MK cam and found all of his speed back plus a little. only changes were reground cams and spring changes.

What sucks is, you and I got pretty heated with each other, basically over Bob and the bs. We are local to each other, and generally , should have been on the same team. I too was bamboozled by bob's words, advice, and what not. If bob said it, it was gospel .
We should be helping each other out, to avoid issues here, and in person, as thats what boaters used to do. Bob did a good job of dividing everyone up. You were either with him, or you weren't. Either way, glad to see your post.

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!
Kinda looks that way, good eye!

Some of us been here on oso quite some time. For me, 12 years now .
I cannot say, that I recall, ever seeing a picture posted, video posted, of Bob doing anything. Building an engine, tuning an engine on dyno, tearing down an engine, rigging a boat, or anything remotely related, to what his website leads you to believe he does. Has anyone else?
