Is this what the Morels usually look like?

They look like 5315's to me. Is that a film or imperfections in the body where the lifter tray hold them?

Those are machining gouges. I sent them back. I am wondering if this is typical or if QC was asleep at the switch.

Must be asleep because mine did not look like that.

Morel 5315 user as well. Other than the dings, they do look to be 5315's. The scuffs are actually a bit suprising because quality is usually excellent. Well good luck with the new set. Still a good lifter choice my book.

Thanks for the reply. I'm going to try something different. I've lost whatever interest I had in Morel after these. You know, fool me once.....

Where did you buy them from? There is a place that buys them in bulk and always have problems with there handling of the product.

Texas Speed and Performance. But Seth was fantastic in helping me out with them. When I told him about the issue he said "send them back" and isn't charging me a restocking fee. Not at all impressed with the lifters but great support by the guys at TSP.


And I'll add - these marks aren't from bulk handling. This is definitely a machining/finishing issue. Its like they weren't completely finished before they went out.

Hey John, I was about to order 5315s myself till two things this week:
1) one of the big sellers on this forum that sold many of these is now phasing these out for a newer "2017 model" that makes me wonder why the change needed if they are so much better than the ls7's???

2) your issue, wow!

What are you going to get now and what rpm will you be turning with your stroker?

NC_John

Hey Chuck! I am going to go with the LS7 lifters now. My builder uses them on 1,000 hp race engines (circle track and road course stuff) that see over 7,000 rpm routinely and hasn't had any issues yet.


My callies compstar bottom end should be good for 7,500 RPM as long as the valvetrain can keep up.


These are the guys helping me with my build - RF Engines and Development in Concord, NC. They helped Circle Track magazine with this build:

I have sent the pictures to Morel and yes that should have been caught. I will make them aware of it.

Based on what the OP has put for max rpm I would not run a .700" wheel lifter in any brand. Drop in I would use a Morel 4708 with a .750" wheel.

Morel wants it back. NC John I appreciate you bringing this to our attention. Each box has a shop order on it and that tells who the inspector was for that set. It will be addressed with them. The last line of QC is the end user and thank your for your effort.

I would be happy to send you a free T shirt for your efforts.

Chris, thanks for the reply and recommendation on the lifters.

Here is the end of the packaging (on its way back to TSP).

Hey Chris- what's the thinking behind running the 4708's and the larger wheel? More needle bearings to share the load at higher rpm? I noticed they can be used with the stock lifter trays so it can't be a concern about a lifter turning. I'm sitting talking lifters with a nascar engine guy (cup level, big teams) at our kid's karate class and we're wondering.

Thanks

Thank you.

The larger the wheel the more reduction in the pressure angle. This makes for a happier valvetrain. The larger the wheel the more load capacity it has for more aggressive cam profiles. Most after market lobe profiles are designed using a .750" wheel.

The body of the 4708 is machined from bar stock. The needles and axle assembly are based on technology Morel has developed with Hendrick's. Morel and Jesel are the only 2 lifter Brands that are used in NASCAR.

That makes sense. Thanks for the explanation. I asked my guy if the cup engines used bar linked lifters and he said they were actually slotted/keyed to prevent rotation.

Cstraub

iTrader: (1)

Correct. The Infinity and the Truck Series have been roller cam and use a keyway lifter. The Cup series went back to roller cams in 2015. They run a .936" lifter with needle bearings.

Below is a picture of set of Morels out of a NASCAR engine:

Very cool stuff. I barrage my guy with questions every karate class with what they are doing.
