I just got off the phone with Jared at BTR and I'm looking for opinions of these two drop-in lifters. The 2110's are over twice the price of the 5315's, and Jared said they had reports of the 5315's being a little noisy when they are cold. Any other feedback on how I should choose one over the other?

When you use link bar lifters instead of the trays, can you still use the thin rod trick to keep the lifters from falling during a cam-only swap?

Well...you're sort of comparing apples to oranges. The comparable Morels are the 4708 or 4793 drop-in lifters.

I didn't know that the morel 5315 are noisy on cold start ....
I'll look into these before I invested in the Johnson lifters due to the price.....

I'm not trying to compare the exact same type of lifter. I know I prefer to get rid of the plastic trays, but some of the link bar lifters are uber expensive.

My upper RPM limit will probably be 6500, and I plan to have an endurance cam below .620" valve lift. For valve springs I'm leaning towards BTR Platinum duals, PSI LS1511ML beehives, or Comp Cams 7228 conicals. I'm planning to use the Manton 5 series pushrods.

Suggestions on lifters?

Ive never had a morel lifter from any brand (morel,comp,lunati) make noise on a cold start. IF there is one report of this it could be due to many reasons not related to the physical lifter itself such as: low weight/wrong weight oil, low oil pressure, higher than normal clearances on bearings, fuel fouled oil, bad engine bearings, pinched o ring on pump, not enough oil in the system due to leak, blowby, bad seals. We have literally sold over 75 sets and zero have had any noise complaints.
If you want a good quality cast lifter the 5315 is it. If you want a better quality machined body lifter the 4608 is a good choice but i would go with the 5206 and get the added rigidity and reliability of the tie bar.

Endurance cam below 6500 would necessitate a tie bar lifter imo. id look at the 5290 or 5206. The plug is we are running a gp on the 5290 and have the best price on the 5206 here.

I certainly like the price point of the 5290 better. Doesn't the 5206 have the tight tolerances which means you have to be more careful on which oil viscosity you run, and running the risk of tinier particles in the oil causing lifter problems? The Lunati 72332 is just a rebadged version of the 5290, correct?

No the 5206 has normal tolerances. they are not the "high rev" lifters. you can run .050-.080 iirc on them just like a normal ls lifter. some will tell you .040 but i dont believe that is enough preload.

as far as tinier particles? that seems like an internet myth to me.
i am not sure on the lunati i would have to look them up. We have the 5290s on gp right now for less than $350. pm me if you want to get in on a set.

As far as I've read the 72332's are the same physically as the 5290's, just re-badged. If I decide on a link bar then I'm leaning towards 72332's because they tend to be priced $30-$40 less than the equivalent Morel's. A sponsor has them for $320 right now, for example.

Lunati did have a price increase at the first of the year. Maybe they did not get the memo.

I do not know if they are just rebadged or not, but when a manufacturer makes parts for another company, they usually do it to their specifications. The bearings could be different, the material of the lifter, a few tolerances could change. Maybe none of it matters, but there is usually a reason for a decent price difference and the difference is usually more than a name.

What do those have to be called "HD" and to be $50 more than regular LS7 lifters?

I went with the 2110 johnson slow leakdown rate lifters from jared on my ls7 build. It will be done soon but I went with the btr stage 3 and plan on around a 6800-7000 rev limit. I called the guys at johnson and talked to them about there lifters for the the preload spec and rpm limit. The guy I talked to there said they was doing some copo testing the day before I had talked to him and said they were running them up to around 8500 rpm and the was less the .002" valve bounce lol. Ill have to look up the guy I talked to but he was great to talk to. He recommended .035-.050" preload, I think he said the copos are around .050". He also recommended manton pushrods but I bought the btr cam kit which came with btr pushrods, I might go to mantons later. The way I seen it if there good enough for the copos then there good enough for mine.

Any results to share from your testing?

While some of his info was stretched (or misunderstood)...it's not stretched very far. Like most dynamic tests, there are fuss points. How much and for how long, goes far beyond the scope of this thread. Some of that "fuss" can be derived from a number of issues, valve springs and cam design being the forefront. Regardless, there was nothing more than .010" bounce up to 8300-8500. Some OEM lifters can hang in there too. But is the entire set consistent? For how long are they consistent? How much spring? How much boost? Etc.

Also, other design enhancements excel in durability. Dynamics are only half of the story, but gives you a good idea if there's a problem that can lead to durability issues. Running on a SpinTron without any forces on the valve brings in another element to the equation as well. SpinTron's are just another tool in the toolbox.

Do you work at Johnson and were you the one doing the testing? Which springs were you using and what valves? There are many "fuss" points indeed. What brand/weight of oil? What bearing clearances. The list goes on and on. Those are only a few you did not mention.
When you play telephone you lose alot in transition. I have not been graced with an opportunity to be near a spintron or operate one. Like you said they can only simulate so much. Otherwise you are based of what real world measurements you can get, the accuracy of the tools and the person/computer measuring them, as well as any theoretical calculations you would have to use to come up with forces and measurements not able to be taken. A running engine on a stand/dyno and a running engine going down the track for instance will be 2 completely different animals. Even an engine on and engine dyno vs that same engine in a car on a chassis dyno will be different as far as that goes.

CoSpeed, I would like it if you would clarify a few things. I have seen you post different answers for the same questions across several threads. In one thread I seen you post that .40 preload and 6500rpm max for a 5315 and in another thread you posted .60 preload and 7200rpm safely. Which is it? Thx

Tuskyz28

Johnson drop in lifters are way high assuming the 2110 is still a drop in lifter. You can dam near go ahead and buy a link bar lifter and be better off in my opinion.....

I am not sure where I posted. 040 was ok but i prefer .055-.060.

Ok I have mine @ .60 which is what I thought you told me...just double checking.

Thx
