Lunati cams being phased out?

If comp is affiliated with the same parent company that comp is, then it’s possible comp could have the lunati profiles.

But if the lunati profile is ground by comp on one of their **** cores then what is the point. May as well throw a handful of metal shavings in your engine and get ut over with quick.

Comp has ground them for a long time now.

What makes you say Comp uses **** cores? How many cam core manufacturers do you think there are?
 
Yes Comp has been making them for a long time. I have never been impressed. There are better companies out there. Still Lunati had a great of the shelf grind that worked. Just like always... they are better so buy them and shut them down.

Well for one I just had a customer that brought me a cam for his build new in box. It did not fit in the block. It was very tight and did not want to turn at all. The when I checked the timing gear it was way to tight as well. It was not machined correctly or was bent. Plus it looks like ****. I got a Summit cam and it fit and was smooth as silk when I turned it in the block. The block was just cleaned and new bearings installed. I went and tried one other cam I had in the shop and it fit perfect. So I know the new Comp Cam was the problem. Now if you can find the older cores they seem to be OK.

Was the problem with the core or the machining itself? Serious question - how many cam core manufacturers are there? How would it be that Comp is the one who uses **** cores, but the cores all others use are fine.
 

I do not know. I didn't put a micrometer on it. I could tell as soon as I took it out of the box it did look good. I tried it but did want to bugger up the new bearings. So I tried two other cams I had on hand. No problem with them. I tried to fit the timing gear and it was so tight I would have to had to smack it with a hammer to make it fix so I stopped. I would say machining but would you trust that core? Not me... no way.
 
Now I have older Comp cores, Plus I just bought a new Comp Cam from a member on here but it was the old core with the CWC on it. It fits fine. I just don't trust them anymore. Hell I've had better luck with the Summit Racing cams anymore.
 
You shouldn't have to polish a new camshaft to get it to fit in the block.
 
Comp, [ & the others ], do not make cam cores.....

I have had cam cores where the journal diameter was slightly oversize. Had to put the cam in the lathe & take off a couple of thou.
