How is tim , pulling his engine apart, inspecting, taking photos, sending them to cam motion, other cam companies, randy at johnson lifters, looking into hardness checks, and posting here, in any way, poor due diligence?

Bck, i didnt see you quarterbacking the guys whos idea of due diligence, is "i called bob, he said i will be fine " or "i called cam motion, they said ill be fine" . Yea, thats pretty scientific.

That's true not one person has had a cam even close to mine and say how long it's lived..

What about my post is untrue? Many people other than myself have pointed out his exhaust is a limiting factor, his carb and intake is a limiting factor, his dynoing with full accessories is lowering power. Are you saying his exact combination of parts and dyno set-up will make 700 if he changes a cam? His engines don't make 700hp for half a dozen reasons, the cam being just one of them. As far as lobe damage from the profile, well let's hear it.... This post has said very plainly that the damage has been caused by all the following reasons- improper grinding. Improper heat treating. Improper final surface polishing. Poor lobe design. Insufficient spring pressure. Improperly indexed lifter bores. Lifter wheels not squared in body. I don't even see where the extent of the damage has even been properly verified and stated yet. First the cams have grooves. Then they just have discoloration. Then they just have a funny looking surface. All these pages and I don't even see where the actual damage has even been properly assessed and stated yet let alone the cause.

I ha e posted every last little detail about my engines in and out, specs, build sheets, pics... As far as figuring out what's wrong? That's easy, heads, cams are wrong... Totally wrong... Gonna work on that this winter..what are your can specs? Please let us know so we can compare... You made such great power but inreality not much more then me if I went Dyno trim and did fast sweeps, I would love to see cam specs... Or pics of your cams after 65 hours, spring rates, and installed heights.... If cams are close to mine

I suggested pages ago that due diligence in this case would be sending the cams to cam motion and finding out directly from the manufacturer what was wrong and what the likely cause was. It was you that said matter of factly that Cam Motion could not be trusted to diagnose their own cam.

Cams will be sent out when ready for "precessional" diagnose, I am very busy this stuff didn't happen over days for me...

As far as 700 goals not possible with my exhaust and induction? Well maybe Bob should have said dude that won't happen, but because I was spending money he made that claim a point that it will... Want me to post that sheet again? "Expected hp and rpm" 700....@6000

I still suggest he sends one of the cams to an independent cam grinder for analysis.

He also called cam motion last year, and was reassured he will be fine. And yet, here we are.

He was willing to deal with a slower boat, if it ran good and was reliable. Now , he has not only a slower boat, but an unreliable one as well.

Did you gain speed with your new builds in the boat ?

Let me be more specific. When I say what's "wrong" with your engine I am referring to damage, not power. I don't see yet where the damage has been accurately assessed and evaluated. I believe the only correct assessment of what damage has occurred to your cams is going to come from the manufacturer of your parts. Every possible cause under the sun has been put forth in this thread. As far as me posting my specs, you're kidding right? Did you read the threads I've started in the last year about these engines and the parts and the dyno pulls?

bck

I have not blamed Tim for any of his engines problems in any of these multiple threads he has started recently. I have not defended Bob in any of these recent threads. I've done nothing but offered helpful advice to the extent I'm able based solely on my limited dyno experience with my combination of parts. Reading comprehension is a strong point of mine and I stand by my above post that nothing here has been properly diagnosed yet and virtually every cause under the sun has been put forth .

bck

People keep bringing up my power and my parts and if I will have problems after 100 hours. That's just deflection. My engines and what problems and power I might make has absolutely nothing to do with what is wrong with Tim's engines. My engines may or may not last and might only make 600hp. That doesn't change the fact that the damage to Tim's engines has not yet been accurately assessed and stated in this thread.
