I just got a Lunati cam and I don't see where it tells me if there is advance ground into the cam.
They call for 104 ICL with a 110 LSA so they want 6*.

The cam card lists the grind number as TF62-TF62-10-A
Then below that the grind number is called out as 04-TF62-TF62-10-A01

Does anyone know if the 04 preceding the TF62 means it has 4* advance ground in??
 
I emailed them and it's taken back and forth emails half of the day to get an answer. First they sent me the cam specs (i already have the card), then was told they want it 6* advanced for a 104ICL. I had been asking specifically from the start "does the cam have advance ground into it"
Finally got an asnwer, the cam should have 6* advance ground into it. I'm def gonna check that out.

...and this is why you just CALL them and get the answer you need. Emailing sucks when you're trying to get specific information. And it doesn't take half your day, then.
 
... this is why you always degree the cam, regardless of what someone said on the phone! Don't just line it up dot to dot.
 
If you line it up dot to dot it SHOULD go in at 104 but it needs to be degree’d otherwise you don’t know where it’s at.
 
You can call Jesus and that's not gonna do you any good. How many degrees ground into the cam taint got nuthin to do with nuthin with "WHERE" the cam will end up installed in YOUR engine. The only way to do it and know FOR SURE where the cam is, is to put the wheel on it and degree it. Usually when people ask if the cam has advance ground into it, they are hoping they can just stab it in and go. IT must be degreed if you want to know where it is, and that's just the long and short of it.

Could not agree more ! Forget all the emails and phone calls !! Just degree the cam in and be done with it ! Degree your cam, it isn’t the voodoo science that a lot people want you to believe !

That's a FACT! In fact, all it is, is grammar school geometry.
 
I will degree the cam. But i wanted an idea where to start and if i absolutely needed a timing set with 2* increments to get the 6 advanced.
Also was told over the phone before i bought the cam, it is 162* @.200 then in email today i was told it’s 160*@.200


So everyone else running lunati cams. Your cams had the advance ground into the cam?

LoL. Cams are like underwear, are changed daily.

You can get a cam ground any way you want it.

Get a degree wheel and watch some Utube...

None of that matters, what they told you, or what somebody else told you, or somebody tell big you anything ! Degree the cam in , you will know all your numbers ! I would buy the billet timing chain set with 9 key way adjustment ! Degree the cam , use the key way you need to get the cam to 104 icl I think is what your cam card said ! I guess I’m telling you , there is no need for the info you are asking ! When you degree your cam , in your engine , you will know what you need to do ! If it comes in at 104 then leave your timing set alone ! Straight up is what you need ! If it comes in at 108 , we’ll you know you need to advance it 4 degrees ! Just degree the cam and your question will be automatically answered !!
 
Let me see if I can clear it up for you. Every single aftermarket camshaft made that the cam card reads for example, LSA=112 Intake center line (ICL)=108 HAS advance ground in. In the example I gave, that camshaft has 4 degrees advance ground in.

That means in a perfect world, if you install it dot to dot, it WILL be ICL 108 degree, or 4 degrees advanced from the 112 LSA.

Since it's nowhere near a perfect world, they very, very rarely work out installed dot to dot, so you need to degree them.

The only situation where a camshaft would have no advance ground in is if the card reads the same figure for the LSA and the ICL, which is unusual, but does exist, especially if someone is custom grinding something for a given application. There are also cams that are ground retarded, but it's pretty uncommon.

Yes, install straight up and then degree it to double check.
 
I've had a solid roller cam from their Voodoo series since March. I'm done with them. Poor communication, and no updates on my order. I'm looking for a big solid roller cam and lifters. Not to hijack the thread, but looking for advice from the members on this site.

This is all I was trying to confirm. I was thinking the cam card was saying the cam should be installed at the recommended ICL but if you install is dot to dot your gonna be real close to you LSA, no advance...

Can you post the cam specs.

i posted the link but actually, one better.

No, that's not what's being stated.
IF everything is indexed perfectly as machined, dot-to-dot is going to install the cam with the intake centerline at 104deg ATDC, not the "straight-up" LSA of 110deg. You check & correct it 'cause it ain't a perfect world. The tolerance stack-up can put You off 4deg real quick, crank keyway, crank & cam sprocket keyways, & cam keyway,(or dowel pin/hole), can all be off. Worse/more critical on the cam end because that error is multiplied 2X at the crank.

No, you're not understanding at all. You're wanting to hear "put it in dot to dot" and we're telling you the exact opposite. Here's why.

Timing sets and camshafts are "supposed" to be cut to match up. Remember that "perfect world" I spoke of? They never are the same. That's why it's so important to put the wheel on it and degree it. I've had one retarded 11 degrees before degreeing it years ago. I wheeled it about ten times to assure it was right and it was. How do you think that would run? Like crap.

If you degree it, it may be right, but the chances of that are slim to none. You go ahead and do what you want. I hope it works out. If all you wanted was a bunch of yes men, you're in the wrong place. We tell people the truth and try to help them make right decisions.

All he wants is someone to tell him "just stab it in, it'll be fine".

So here it is. Just stab it in. It'll be fine. lol

...and honestly, @cookietruck I hope it is fine if you just stab it in dot to dot. For your sake. I would just guess the odds of that are probably over 10,000 to 1. THAT is why we recommend degreeing it. Good luck with it! Over and out!
