It should be impossible to get that kind of finish from a grinding operation - it looks to me like the final grind operation got skipped.
I just looked back at the pictures (#025) to see if the bearing journals have the same problem - they don't. The lobes should have the same finish the journals do and they are not even close - this is a manufacturing error IMO.
A "blower whine" noise after cam install is NOT normal. If you installed an FMS cam and suddenly had this noise I would seriously consider pulling the cam and checking it before it destroys itself and the lifters and spreads metal throughout the motor. Even if there is no serious damage yet, I would still replace the lifters if they have been run very long at all on a cam with this kind of surface finish.

i have that sound, but i also installed a used ASP underdrive pulley. When i push in the clutch, the blower whine sound goes away immediatly though. is there anyway to tell that mine is comming from something with the cam and not the pulley? I didnt put the cam in, so just to get it checked out id have to pay to have someone take it out and put it back in, sicne i really dont have time to do that, nor do i know exactly how. I ordered my cam when they had the 10% off all cam and cam packages.
thanks,

The F11 I bought from them in December had some pitting on the journals. Had some mechanics tell me to install it that way cause it "wasn't that bad" but I sent it back to them thinking that it would continue to erode and cause the type of damage you've now had. They finally (long story I'm sure most of you know about) sent a new cam back to me. The new cam had a completely different look to it between the lobes and journals, like it was a different type of metal or process to make the core. At the time there were about 7 or 8 cams that were faulty and I've seen some posts here and there from others that had similar issues with their Futral cams since then.
I inspected the new one with a magnifying glass before installing it and it doesn't have the whine your describing so I guess I feel safe.

Well ****, mine sounds like a blower too. Not that loud but it's there. New about the F13 whine but never really cared since it out down the power.
Guitsboy-
What were the original symptoms that made you pull the cam and then the heads?
Did you noice a loss in power and then pulled the lifters?
I have about 7K on mine and bought it in Dec 2004.

Now i am concerned. I installed the f14 and have had the blower whine ever since i installed it. Guess i will have to look into it. Looks like i am 1 of many who have this problem. ****!!!!

Not sure what the "blower" sound complaint noise is from,but I find it hard to believe that the grooves on the lobes that a few are pointing out is making the noise. Not saying it can't happen, but we have yet to hear any noise like this after an install done here. The only thing I remember ANYBODY complaing about was the whistle noise from the T\B.
If anybody gets\has a cam that they feel has or might be an issues,send it back and we will have it refinished or replaced.
Thanks,Allan

Thanks you for offering to take a look at my cam. I am interested in hearing your opinion. Ill be shipping it in shortly. Ill also include my lifters if you think it would help. Im not necessarily looking to get a new cam out of you, im more interested in hearing your thoughts on the matter. If you do feel that the cam was at fault, it would be great if the cam could be reground though. But like I said, im not looking for a handout.

when I was running my crane gold rocker arm in conjunction with a 220/224 cam I too had the whining squeeking noise. And it too went away when the clutch was engaged, or when the RPM's climbed. It only happend around idle, and only when the oil reached 150 degrees.
I think how tight the crank pulley is on the snout of the crank has some affect on this. I had my car on jackstands and the whining noise seemed to be coming from the bellhousing area, so I assumed the flywheel may have been off balance, but that wouldnt explain why it only did it when the motor was warm.
Sooooo, after the cam swap, no squeeking, BUTTTTT, the crank bolt wasnt tightened down enough, and it came out. Sooooo, now that were gonna get it in there good this time Im praying that ******* whine doesnt come back, Im positive its crank bolt/crank related.

Instead of waiting for people to send in their defective cams and exposing yourself to the liability of widespread engine damage, you might consider trying to determine what serial numbers, model numbers, and/or manufacturing dates might have had this problem and proactively contacting the owners.
This is NOT a bash - believe it or not I am trying to be helpful to both you and your customers. Assuming the pictures are indeed of one of your cams, I am sure that you know as well as I do that this problem will not go away by ignoring it - ALL cams with this problem will eventually break down the lifter rollers and self destruct.

I have that sound a little also. But I am sure it is coming from the gattor back belt.
You could pull the belt off and start it up cold and let it idle (for a short time of course) to see if that eliminates it.
Also if you wanted to just check if the cam has the texture that people are mentioning you can simply pull the intake and the valley plate covering the knock sensors and look in the windows in the front and rear of the block at the lobes visible. IMHO I would start there long before pulling a head or the cam. "IF" the ridges are there what you do from there is up to you.
