F13 & Bad Lifters
Is that even the # to reference???
I have been waiting for a response to see if that is even the correct number to tell.
According to Cam Motion the number to reference is on the BACK of the cam.
Can someone with the cam out of the car note the number on THE BACK of the cam!!
If that core number is on the front or just off the card it might not even matter.
From my understanding there should be a grind number, a core number and some others, But as to the one that She told me would need to be referenced is the one on the BACK!!
None of us know or can presume to know at this point. If anyone knows FOR SURE or has a number that was confirmed to be good or bad then and only then will any light be shed on this.
Also, for the record I miss the GP, I purchased it (or it shipped) in or around MAY 21st. Sorry Nick, I was going to get it then but I procrastinated on the GP like you and the SC! LOL

THANKS!!! That makes so much more sense!!!! So it is probably just referencing the LS1 core for FMS and NOTING to due with the actual core used during mfg or the time when it was produced!
So we are still just waiting to see the # off of the BACK of the cam and a time line given by CM or FMS!
Again,
Those that have pulled their cam if it's bad please post the number on the BACK side of the cam.

I have 332 HP at the wheels and 380 torque at the wheels with the flattest chart you have ever seen. It's pretty much linear. The dyno started recording around 4200 RPM and it's already at 332 HP and goes straight across the chart and stays there. Torque does the same, shoots right to 380 and stays there, drops off a little. It's pretty torquey, lots of fun on the street. If I did take the cam out I would maybe go to the F13, but I want the low end and mid range of a 112 LSA so with my A4 I might be better off with the F11 as far as idle is concerned. Some people are concerned only with the highest HP they can get, but I don't want to have to spin this thing to the moon to use it. I can pretty much light them up at will. I'm sure I could get more out of it with heads, intake manifold etc. but where does it end? It's plenty fast for the street. 
Do you have any numbers yet?

I hear what your saying about spinning to the moon,that's why I went F11 instead of F13 also.
They used a Dynojet. I see what you mean though, you should have picked up something over the B1. Still, you have some nice numbers though.
I actually was looking at that number on the cam, its extremely hard to read as it wasnt stamped very well...I actually couldnt even read 2 of the numbers. I cant look now as the cam is already at FMS.
I was actually inspecting my cam and I noticed slight "skid marks" for a lack of better words on the lobes. Is this the first sign of the things to come or is that just normal? I'll take pictures and post them later.
How would polishing the cam solve the possible issues with the metal? And wouldn't polishing it take some material off the cam, therefore making it smaller? I'm probably going to send mine in, but I don't think I want a polished replacement.

Cam Motion and I can not see or know of the problems before hand,just take care of the problems and resolve them. The given core company also supllies the LS1 cores to Comp. We are working on the batch codes and are taking care of the cams that have issues(replacing with new cams) I have worked together with Cam Motion to come up with our own cores manufactured by Cam Motion. They will be made from 8620 material(same material used by winston cup and Pro-stock)ground on their CNC cam grinder and completely polished. These new cores will be used starting in 2 weeks. Any body that has a current cam that they have concerns with and not installed can send it back and we will have it polished.
Now the oil issues,there seems to be a lifter\bore oil issue that we believe brings out the issues in the cam core material and only effecting a few lobes. Yes the cam shouldn't have an issue anyway! But the Morel lifters are helping the oil starvation issues.
Yes we don't make the cams but Iam taking care of repalcing the effected cams purchased from us.
Hope this helps everybody out.

I can see FMS is not being very helpful, go figure. They are still ignoring my phone calls as well. My FM13 bought last year during the GP will be out tonight. I'll post a new thread and pictures. Should be interesting to see what it looks like. 
FMS received my bad cam on the 10th and they are telling me it wont be til the first week of april until I get the new one....I'm with the other guys, FMS or Cam Motion should be on their toes trying to get these new cams out ASAP.
