SORRY FOR THE THREADJACKING!!!

As for some more information...what is case hardening on a cam? I just got a custom ground cam and don't know if it has any case hardening? Otherwise the cam looks great! Very well cut...thanks to EDC

Case hardening or Surface hardening is the process of hardening the surface of steel whilst leaving the interior unchanged. The idea behind case hardening is to have two different types of steel in the same item. This allows a relatively soft, tough core of a component to be combined with a hard (but potentially brittle) surface. Case hardening improves the wear resistance of machine parts without affecting the tough interior of the parts. Many processes are available for surface hardening.
Both carbon and alloy steels are suitable for case-hardening providing their carbon content is low, usually less than 0.2%. Case hardened steel is usually formed by diffusing carbon and/or nitrogen into the outer layer of the steel at high temperature.
The term case hardening is derived from the practicalities of the process itself. The steel work piece (e.g. a firing pin, the head of a rifle bolt, or an engine cam shaft) is placed inside a case packed tight with a carbon-based case hardening compound. This is also known as a carburizing pack. The pack is put inside a hot furnace for a variable length of time. Time and temperature determines how deep into the surface the hardening extends. However, the depth of hardening is ultimately limited by the inability of carbon to diffuse deeply into solid steel and a typical depth of surface hardening with this method is up to 1.5mm.

I just got off the phone with Lunati's tech support (662 892-1500) and they said the 72432 is in fact made by Morel. They also recommend 0.040-0.045" cold preload.

That's what I heard too...
Looks like we may have another "overseas" R&D piece (Rip-off & Duplicate)
I'll stick with the genuine article, thank you!

Chris & Ed,
How much does a Morel weigh off the shelf? I'll be heading to the post office in a few minutes and will have them weigh one of these Lunati's I have. Also, is there any other comparo you guys would like to run on these? I'd prefere not to tear down a lifter, but now is the most opportune time.

Good News!

Could you help me understand where you got that from?

I was told by some people in the know ( w2w and in the ls1 book by Will Handzel) to use the more desirable 2001 and later fully encapsulated lifter, meaning the body of the lifter completely surrounds the roller. Otherwise I would use aftermarket ones as I had to. For some some reason my 2002 didn't have them.

We use and sell this lifter in a lot of builds with great results. Not too many companies out there actuall produce their own lifter. A little more since High lift went under a few years ago.
This lifter is the Morel lifter.

I have no idea where you came up with this point. I know for a FACT Morel mfg all of its parts here in the USA, is a manufacturer, and makes one of the finest products out there. I have stood in the plant on 3 occasions and witnessed the CNC's, grinders, gear hobs, and screw machines working. I have also been in the furnace control room to see how their heat treat facility monitors it's functions. To have 80K sq ft of machines and 60 plus employees standing around as a pharse must make great business sense.
In addition, Morel ( Gear Co) has been in business for over 60 years and has been a supplier to the OEMS for over 50. The company has slowly seen its contracts shipped overseas to foreign labor. In a attempt to keep American workers off of the unemployment line, Morel got into the automotive aftermarket with an old style approach, hands on company owner under the hood trying to improve parts. It is an absolute insult to Morel for you to even post WTF you did.
Futhermore my reputation at the end of the day is all I have. I don't come on these boards as a "keyboard Rambo" and post BS. I work in this industry, have alot of contacts and have a good grasp of what goes on. If I tell you something you can take it to the bank. Morel has nothing to gain by lying to me, but would have a lot to loose.
As far as I am concerned if your type of post is what is going to posted, then as far as me helping the the board find out what is what I am done. I am satisfied with what is and what isn't.

*edit*- I just remembered you are the one helping Mester with his engine/top end. Did you give SDPC a call to tell them how to do it? I cannot wait to see the results from that beast!
