Those are the only ones we can really get regularly and we use them a lot. I have been waiting a few months on some of the other Morel lifters but the main-stay link bar they have (5206) is the one you usually can actually get.
Thanks for the info. So you haven't seen or heard of any failers with the 5206s?
Just bottoning up my 447 with the Morel 5206 link bar lifter from Chris at CC Performance. Is 60 thousands preload going to be ok on them? I think we measured 122 thousands till bottomed out so we were thinking that 50-60 thou should be good? Whats your thoughts on this Erik??

Cool, thanks. I guess I should have reworded my question but you still answered it. I know all parts will fail eventually I was look for specific failures. Thanks again.

Hey guys since january i've had the lunati linkbars in my LQ9 408 an it had never been an issue until lastnight the valve spring problem they are 3 years old on a 650+ lift camshaft daily driven... lol Ls motors are the **** hands down... The car is a 408 M6 heads/cam car with a stock L76 manifold & TSP 92mmTb an it made 546/513 to the tire with a bad lifter an shitty valve springs. The car runs down 1000cc bikes after 100mph with ease. I think the lunati lifters are awesome i'm just not sure if it's the valve spring or the lifter that has failed, but with shifting at 6800rpm when the cam redlines at 7500 it makes me wonder... I'm sure the valve springs are the culprit here after 3 years of daily driving all season weather... lol I will keep you guys posted though after monday when we pull everything apart on the top end an look it over. It's so nice to find the exact thread your looking for when your having similar problems with a build +1 Ls1Tech & members for supporting the world of motorheads!
Haha I agree!
Well keep us posted. I'm almost complete with my build. Just need a few parts and I should be done by the end of the month, just intime for the holiday! Build in my sig.
I hope it's the valve springs and a quick fix.

Yeah man me to because i couldn't imagine it being anything else really because when the 347 with patriot heads **** a valve spring it ran the exact same way so i'm leaning strongly towards the problem being that or atleast i hope so... We've both been after almost the same info on alot of things with these stroker builds still trying to find a aftermarket intake and a set of roller rockers. lol
Yea thats funny about seeking the same info haha
I got my fast 102 last week, my buddy chrs1313 is going to port match the runners and check for my correct pushrod length and PTV clearances.
I still need that kooks ypipe because I got the 2" primaries and they have a 3.5 in collector and that's $$$ haha were almost there lol. I'm shooting for late June but we know how that goes.
Anyways back on topic and awaiting those results.

ok, so I'm still a little fuzzy on this...
Lunati 72332/Morel 5290 are only good for 6500 RPM's...= $380
LS7 lifters are good for 7k+ = ~$150...
anyone care to explain?
If i can figure out if the Lunati/Morel's are just as good or better than the LS7's at 7k+...I'd rather have them because I can get rid of the lifter tray and have a more reliable lifter...if thats the case. Otherwise, I'm sticking with LS7 lifters.

In other words...does GM publish a 7K+ RPM spec for the LS7 lifters, or are you going with what Teh Intarwebz says?
More or less the fact the ls7 already red lines at 6800 and many, including myself have taken them to 7k + without problems. I'm just looking to upgrade.
On a side note, I spoke with one of my good friends that works at lunati and he tells me he has put the lunati streets in engines turning 7500 on a regular basis without problems. Plus, he can get me a significant discount on them and the lunati dual spring kit.
Go me!

Would you be able to ask him what preload he prefers on 72532LUN lifters? These are the more expensive micro-polished super duper ones, and there is a great deal of conflicting info on preload requirements for them.
