The plot thicken's, so does John own Morel? If so, is he then simply another customer of the "Gear Company"?
John either own's Morel or is a shareholder in Morel as I have an email from him with regard to a query I had on Morel's solid lifters. And have spoken to him on two occasions about the same subject.

A Morel dealer claimed that he visited the Morel factory which is majority owned by John Callies [the founder of Callies crank's] and that I would be shocked if I knew the big brand names that have their lifters made by Morel, and many to their design, so that they are not simply re-branded Morels. When I mentioned to him that I was running the Johnson's he said "yep their also made by Morel to Johnson's specifications"
The companies that rebrand Morel lifters. Lunati, Bullet, PBM, Howards cams (?), Straub.... motorsports unlimited, some comp, I believe many comp's lifters are made by Johnson. Basically the whole point of this is these companies are to provide the customer service, they're camshaft experts.
Funny I was driving to PRI think '09, started to rain saw some guys taking cover, I'm like hey, going to PRI get in, it was John Lewis from Johnson/SEC, so yeah we had a chat. You may want to call him if you have questions.

He may have been mistaken regarding the Johnson lifters, that company actually has their own manufacturing.

! I'll have to ask him about that. His name is Joe Lewis, and he's the sales manager. Yes, we manufacture our own lifters. Comp used to buy lifters from us, but hasn't in quite a few years.We kind of went off on tangent here. Back to the OP's question...spinning a hyd. roller to 8k. It can and has been done...but as was mentioned the airflow and a well thought out cam profile to support it is the largest concern. In high RPM road course, or big boost applications I always recommend shaft mounts and short travel lifters. IMO the geometry and scrub benefits you gain from a roller tip rocker is ideal in these arenas. Also the added strength on the exhaust side for boosted engines. I personally like Crower's stuff. For this build upgraded stockers would do just fine and yes they are easier on components due to their weight. Hell...the COPO does fine with straight out of the box OEM rockers (not that I agree with it).

At 8000rpm, what specifically makes one HYDRAULIC lifter any better than the other? Hydraulics are hydraulics. I would like to see this issue broken down in detail.
Generally, the engines we run are not very cheap. That said, I don't really see the point in putting a lifter in that could in theory collapse and destroy the engine.
I think the solid roller lifter is less likely to do this and a better option especially for someone wanting to spin 8000rpm. I wonder what the NASCAR guys use. If its hydraulic, might be something to copy.

Good luck w/this venture but I'll add the following.

Indeed NASCAR does not use Hydraulic Lifers.

As of a few years ago sprint cup cars ran solid flat tappet, 2015 rules bring roller lifters to cup cars. Nationwide.. Xfinity now run solid roller lifters.
Australian V8 Supercars I believe are Solid Roller, but rev limited to 7500rpm, fact check this Kiwikid?

You do know who havoc40 is right? He's the main engineer at Johnson; his names randy fwiw. Don't go generalizing things like that because in the end you don't look too smart.
Morel makes lunatis lifters though, I have held jihnsons in my hands and they in no way resemble morels. Toilet and tick will tell you the same thing.

Not sure Brian has been called that before...LOL!

For all practical purposes your contemplating building a modernized DZ 302 more or less. If you reduced your rpm goals a little, your cost would go way down. Low 7000s wouldn't require $$$ parts and still be a lot of fun.

Yes 8K is possible, I have a LSX454 hydraulic roller with trickflow heads and it will spin to 8 grand. Last time I dynoed it in my 2002 6 spd camaro it was over 600 WHP but I need to redo the sheetmetal intake and find me a Corvette to put the motor in and I think I should be able to see 650 rwhp all motor. Its been a goal of mine for a while but I am still working on my Dodge Challenger build to be complete before I get back on the Chevy build again.

No, but that would be funny... 
Check his IP from his recent post. He suddenly popped up and bumped a few threads that were at least 5 years old.
I can't see any of that since they separated the forums.
But I did stay at a Holiday Inn last night!!!
