Generation IV Internal Engine - anyone used the Morel "Street" Hydraulic Link-Bar Lifters

I was Looking for some lifter for my new Build
saw this lifters and wanted to know if anyone used them yet?
the price is lower then other Morel Lifters

The cam i'm going with isn't very aggressive so wanted to know if i could use them?

think the part number is 184-5290-STRT

Im using a LSX block and would like a lifter that is Linked with Link Bar

Don't know if these are the same as the # posted, but they are what I am running in my 402.http://www.mcssl.com/store/cc-performance-parts/catalog/product/d4920f1632ce40428c59fad3a420bc85

I've shipped a little over 100 sets of these this year to LS Shops. I have had not one issue with the lifter.

Thanks im using a set in my new motor
They are a very nice part.

Are you using this lifter in a street car?

yep there going in my street car
full body, all the seats, A/C and heat
car is about 3800 and auto

should have the motor on the dyno next week

I have a morel w/ pressed in link bar that gave up on me, if you or someone you know would like to take a look at it I would appreciate it.

maybe 7000 miles on it, comp 921 spring and 600 lift at the valve

My friend had a track engine built with these lifters and one just failed. the engine had 17 hours on it. Not so sure this should have been speced in a race engine.

What kinda lift was he running?
How big of a cam? How much pre load? How much RPM?

The lifter is designed to for street cars with the occasional pass at the the track. They are not built for all out race cars. Still would like to see the lifter.

MightyMouse, I'm curious what failed on your lifter...part of the link bar setup, or the internal plunger?

Reason I ask, is I'm building something that sounds REALLY similar to your setup (an RCH under 0.600 lift, Comp 921's and boost) and I'm shopping for my lifters right now...hopefully going to take advantage of a "holiday" or "year end" sale if I can decide what to order lol.

the rest of the lifters and the lunati version i replaced them with have been fine rest of the season.

i still don't know what happened to the lifter because i have not been given further return instruction from cstraub / morel :(

I think I'll buy the Lunati version, far as I know they're the same lifter...but for an awesome price in comparison.

I'm pretty sure the Lunati is just a repackaged Morel. I had a Comp short stroke lifter fail due to way too much preload. I bought the street Morel lifters for my new cam. I'm going with a less aggressive ramp rate to be able to turn 7500-7700 rpm.

Bringing back, just curious because I just bought the Lunati Version and I'd like to see what results have been had from these lifters.

having owned both, the lunati is the morel but with a little more work.

Thankyou Sir!

I'm going to the track maybe 4-6 times this year so I should be good with these.

I have the Lunati link bar and so far so good. Cam lift is .635 with spings for .660 lift.

Be sure and check you piston to valve clearance as the Lunati's where .100 taller then the Comp lifters ( a plunger failed on one ) they replaced.

Gotcha! Thanks for the heads up sir, I appreciate it.

Did you ship these to me? I don't remember, I apologize. I don't get on here as often as I use to.

you told me above to email you so i could request an rma, i did that and waited, i have just done it now a second time.

in case your email linked to your profile is broken, please do email me

anybody have a P/N for the Lunati lifters?

im assuming they will work well in a 370 with LS3 heads and an MS4 cam?

I'm sorry, let me get this strait.

These "street" lifters cost $500+ and shouldn't be used that much at the track? If you just use it for the street... why dont' you get a street priced lifter? Doesn't seem that the price bought you anything IMO.

Would you not set / check that with your pushrod length calculations?

The "street" lifters are much cheaper about half price or less like 230.00 or so but they are not the same as the regular Morels at all. Totally different lifter.

The $500 set is a production assembled version of the $700 hand assemble sets I was told.

I don't get it. Why would you pay 500 bucks for lifters that aren't ment for the track, and don't go past 6500 rpms. Esp when you can use ls7 lifters for about 400 bucks cheaper and turn 7k often(ish)

I want a set of link bar lifters for about 400 max that I can turn 7k with on a regular basis.

What ref# are you talking about here to point out those Morel :confused: :confused: :confused:

Get in touch with Back Street Performance over in Medina ... they are friends of Ed Morel (Morels are manufactured in Cleveland). He actually just took a look at mine before we reused them in my 427 build.

Absolutely ... Morel has a few different versions.

good man. thanks for the heads up on backstreet performance. last place i went, (cincy speed) had my car all screwed up with the tune.

Street version and High rpm lifters are two different lifters. This thread is about the street version Lunati lifters part # 72332LUN \ Morel MM5290

I bought the Morels for my Ls3 stroker because they are built better that the Ls7 lifter and I don't have to worry about a lifter turning on the lifter tray and I don't think my set up should peak past 6500/6700. Besides my car is a street car and I'll be going maybe 5-6x's to the track.

I don't see why these lifters that look better than an Ls7 lifter won't go to 7k?

Litle88 you shouldn't have any issues as long as valvetrain is good.

Thankyou Sir!
Appreciate your input as always!

I don't see why these lifters that look better than an Ls7 lifter won't go to 7k?
exactly...why would any aftermarket lifter, especially one that costs 4x as much, not do exactly what a stock lifter will do?

i understand more reliable and stable, but seriously, if i buy a lifter other than an LS7 and pay 4x as much for it, it better do 7000 RPM and everything and more an LS7 lifter will do.

still waiting for some magic to happen cstraub. please.

^^^^I miss you^^^^

But yea I agree, I know the high RPM versions are built better and are more money. But for good reasons, they are for the hard core weekly racer turning some high RPM's.

I would stay away from the Morel street lifter. An engine builder I know used them in four or five motors and they all had wheel axles that moved out of their bores causing various degrees of damage. Its my understanding that the company doesn't track production runs and may not be sure when or who they were sold to. If you have to use them, then check the wheel axles with a drift punch in both directions to make sure that they are tight.

Well darn it. Any other info on these axle issues?

I won't return business. Support is non-existant.

Not to get off track but does anyone have any experience with the morel "high-rpm" version p/n MOR-5206? I've been looking at these for my build.

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??

He pm'd me 60, so I'd say your good to go.

Yes you should be fine.

Thanks for the info. So you haven't seen or heard of any failers with the 5206s?

I've seen failures with all parts but not many on the 5206s ever besides a few that the plunger stuck or collapsed but the lifter never had issues or came apart.

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.

Yes you should be fine.

Thanks:chug:

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 shit 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 shit 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.

You're comparing Morel's recommended RPM limit to hear-say info on the LS7's, no?

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.

I can, no prob.

I can, no prob.

Thanks very much!

I have asked him about lunati lifters vs ls7's, comps...etc and he recommended the lunati. However, he is a sales person so.....you know. And I'm a big fan of impartial opinions, and I hate when I call certain vendors on here and ask a simple question and I'm repeatadly tried to Be sold something...

That's why I'm asking here about reasons to use the more expensive lunati lifters over the tried and true ls7's.

That's a reasonable approach. In my case the deciding factor is the difference between Made in Mexico (LS7) vs. Made in USA (Morel/Lunati).

.010 to .020 is the preload he recommends. He said everyone has trouble setting them up for some reason. I'm assuming because of the short travel design.

Short travel lifters are very hard to work with if you don't have an adjustable rocker for sure. The main difference on the true Morel lifters to me are a more robust build quality as far as if abuse does happen. All lifters can turn fairly high rpm with good valvetrain but if you get some float or over revs etc. the Morel body and wheel and axles etc. can take a lot more beating if it happens for whatever reason.

.010 to .020 is the preload he recommends. He said everyone has trouble setting them up for some reason. I'm assuming because of the short travel design.

Good info, thanks for posting it. I'm right in range, measured 8-3/4 turns to zero lash on the Comp measuring tool and installed 7.250" pushrods.

.010 to .020 is the preload he recommends. He said everyone has trouble setting them up for some reason. I'm assuming because of the short travel design.

That's what I used when I set up the street lifers in my motor.
I've ran the street lifters in my motor with ls3 heads with 621 lift and now with some ls7 head and a 66+ lift cam and haven't had any issues to date. And the motor is shifted at 7000 all the time. the lifters do not like pre loading at all.

That pre load spec is for The 72532's...not the streets.

I just got my 72332 street link-bars and the pre-load spec is .045-.050 for alum block/alum heads

So I would assume .035 to .040 for cast iron block/aluminum heads?
