Here something to look at solid roller is the shiny one morel. And the black one is comp cams hydraulic roller. Same height where they are attached at on the lifters. So I guess one might leave track marks. These are the tie bars cut from the lifters.

I guess it looks like you are pizzed at me, so now another friendship is suffering, I wont post anymore anything about my engines, it does not matter anyway since I don't listen to anyone, if I did things the way was going to from the beginning I would not have even been in this situation, I came to OSO for advice, research, recommendations and it has honestly done nothing but cost me THOUSANDS of usesless results. if I listen to one person, others hate me or tell me I am stupid, if I listen to others the other side says the same.
maybe I am reading into you being upset at me, hope so since you have truly helped me a lot, if you are actually upset at me then I thank you and I will just move on with life, it has nothing to do with "Tim does not wanna hear it" it has to do with last time WAY too many hands into the fire and I am trying to avoid that again, no hard feelings to anyone...
I am just gonna keep the rest to myself I think and hope results are better in April or May...

See, heres the issue I have. Alot of you guys, only know what is posted HERE, for you to read. I have been filled with calls, emails, messages, and so on, on so many of these topics. I already knew what Randy's opinion was on the failure, or issue here was.
Coming here as an Engineer, everyone wants to hear an Engineers standpoint on the topic. But, he doesn't want to say publicly, what, in his professional opinion, is the problem here. Now, I can understand that. However, theres hundreds of people who are reading this thread, also looking for an answer to the problem, and will never get to know it. For years, there have been issues that have been kept off the forum here, issues that could have saved many thousands of dollars, and lost summers of boating time, because of who's wallets were being lined, or whos business was being protected.
I simply mentioned that maybe the lifter, combined with that cam profile, was a possible issue. Tim, obviously didn't care to hear that, or possible lifter bore indexing issues, or really anything other than "bobs cam sucks". It no secret I'm not a fan of bob m, but it be nice to see tim have an engine that can make it past 50 hours. I mean for christ sake, we are talking about a 630hp 540 here. This isn't some new exotic engine build combo, or shouldn't be at least.
Tim's had some good input here from guys like 14 apache, abones, black baja, and several others. He didn't want to hear about any of it. So, yesterday, the lifter topic got brought up for the first time in this thread, and now all of a sudden, the engineer from Johnsons phone was blowing up , and he had to chime in? He's known about this scenerio for months!
Either way, I get it. He's backing his product, and making sure it isn't getting dragged thru the mud. As far as the morel lifters go, I personally, could not be happier with them. They are in my 800hp engines, that have turned well over 6,000 rpm many times. They've lived with closed to 500 lbs of open pressure, and have had no issues. Icdeppl, has them in his 900hp engines, also seen 6,000 plus rpm many times. We've ran 15w50, 20w50, straight 50, thru them. On the dyno, they've seen 6500-6600rpm pull after pull. We pull our stuff apart , neither his crane 8620 cams, or my crower 8620 cams, have lobe wear like some of these photos. These cams have been around the block to, its not like they had one season on them. The lifters were installed 5-6 years ago, and are still going strong. I also have quite a few friends who have ran them for many years, going back 10 years at least, without issue. So, when I hear about how the "forks" are a weak design, and the .750 wheel is useless, I kinda disagree. I'm pretty sure the engineers at Morel, Lunati, Howards, and some of the many other companies that use morel lifters successfully, would also . Pointing out how your lifter is superior, and how companies like isky and crower switched because of quality issues at morel, seems a bit of a jab to me.
I don't think Black Baja, mentioning how those comp cams, looked fine after being in an engine with morels for years, then switched out and ran with johnson lifters, and all of a sudden the lobes looked like they do, was with some secret agenda to bash johnson lifters. It was an observation. One he felt worth mentioning. If I had a set of firestone tires, that were on my car for 30k miles, and looked brand new, and took them off, and put them on my buddys car, and 2k miles later, had worn out shoulders and looked like crap, I wouldn't be looking at the tires, I'd be looking at his alignment.
But hey, everyone told Timmy his engines would be FIIIINNNNNEEEE, and to stop listening to the keyboard cowboys.....just go run them.......Well, they weren't fine. His cams look like crap, and so do his exhaust seats, after 50 hours. Again, a 630hp 540.
Tim, you obviously feel that you have found out why your cams look the way they do, and you also realized, nobody here is successfully running that cam setup, or at least going to post about it. You don't really care to hear any more suggestions on the topic. So why don't we give it one final post about how Bob M royally screwed you over, and put this thread to rest already.[/QUOTE]

And is the comp link bar possibly made by Johnson? I've got my old link bars handy but nothing to compare them to as the Johnson's are sort of under my intake manifold. I lost some power switching to Johnsons with no other changes made. I assume it was just variability with the dyno.

That's good I'm glad your getting them sent out. I would hope they are able to communicate and come to a conclusion without you having to be a go between guy. I'd also send each company part number of spring used at installed heidth. Short blocks going untouched is completely your choice. I'd be really curious as to what's on drain plugs if anything. Regardless good luck with everything.
