I dont remember exactly and my cam card vanished but I do have the 3314/3315 lobes on a 110 LSA and 110 ICL if I remember correctly unless it has the 4 degrees advance.

 

Ok no fun there.

Got any wild and crazy questions for the new thread?

Bret

 

Maybe an informative thread teaching people how to read a LOBE chart.

throw that in the new thread.... I'll see what I can do.

Shoebox, the reason for this post isn't to flame anyone, but to see if it's happened to anyone else so I can act accordingly when I finally get the chance to talk to them on monday. See, when I'm told I got a custom grind and it looks like an off the shelf cam, I just want some kind of reason why that is, especially when the duration is different than what I was told I was going to get. Being told I'm making a whining noise isn't the explanation I was looking for. I dont like building junk and if I dont think I got what I paid for I'm going to ask about it and part of what I'm doing here is research, okay? So far, I've done alot of business with CMS and never had a problem, and dont necessarily feel like I've been screwed, I just want an explanation. If there's something about that cam I'm not seeing I'm sure they wont have a problem telling me, you just have to understand my suspicion...I want the best parts I can afford.

Anyway, I think I see what you guys are saying. Rather than changing the duration, they use an off the shelf cam close to what I want, then change the lobes to something that compliments my heads?

 

Is a custom the same price as a "off the shelf" from CMS?

Bret

 

Why hasn't anyone asked this yet...?

You said it LOOKS like an off-the-shelf cam. How do you know? Did you get a cam card with it? How do you know it isn't what you ordered? Nowhere in this thread is this explained...

 

Here are a few things to consider......

If it is an off the shelf cam, did you pay extra for a custom grind?

There is a part# on the box. If it is mostly all zero's, with only the lobes listed on the cam card, it is custom. Here is the catch... if you spec a custom cam that uses XE lobes & this combo is already an off the shelf listing, you got what you asked for even if it is not "custom". Off the shelf cams are not inferior, they are grinds that have been proven to work well & were mass produced for a cost savings. If you asked for a custom cam with the exact lobes that an off the shelf cam has, you would get the same thing even if they ground it special for you. If you asked for a special advance, lobe separation or duration it will definitely be custom.

It is important that you work with someone (besides a salesman) to get the correct specifications to start with. Talking you into something that a company sells vs. something that you need is usually the problem. Determine what you need, then try to purchase it, this will lessen the "I've got the perfect cam for you" syndrome that I often see. If a company stocks a "custom" cam is it truely custom for your needs? .... Only if they sell a custom package of heads, cam etc. as a fully configured package.

 

THAT'S what I needed to hear. So it is a custom. OK, good. I still dont understand why I was told I was getting a 233/242 and I got a 233/239, but it should work. That's why I got suspicious in the first place. First custom comp cam I've owned. I'll give em a buzz anyway, couldn't hurt to ask.

Ramair95TA, the reason I didn't think it was a custom is becuase the exhaust duration was different than what I was told I was getting, and the other specs I had matched the ones listed on their website. I guess it depends on your definition of 'custom'... I feel more comfortable now. Glad that's cleared up

Bret, yeah, they're the same. Makes sense now that I know what's up.

This thing has a 3442S intake lobe and a 3443S exhaust lobe. 4 degrees advance on a 112. This thing is going to idle tame as hell...hope it makes some power! Should make some good low end grunt too.

 

in case any ones eyes "glazed over" when reading Brets post, he is basically saying that when you get a "custom cam" they are getting the cam that they think will work best FOR YOU. This might be one on the shelf in a box already, one usoing "common lobes" with a slight variation in LSA/ICL/ECL or one designed with some "not so common lobes". In either case, they feel that THIS cam is the best for you.

You are pretty much getting teh cam they feel is best for you. People that wanbna pick their own lobes and design their own cam should call the cam company directly and cut out the middle man and hopefully they have the cam experience and/or simulators to design teh right cam. If not, it always shows up in the end.

I do not feel you were taken advantage of and after reading the rest of thse posts, hopefully you feel better about the purchase. GFive CMS a call on Monday and get with the guy that designed the cam and hge can probably shed some light on it for you as to why THIS cam was the best choice.

Actually no....

All Comp cams other than a COMP SHELF CAM will have 07-000-8 in the part number. Only Comp has cams that fill in that center 3 numbers like 306, 305 etc....

Combo has lobe/duration/advance combinations that are custom to them so you are most likely going to see a 07-000-8 on all of their cam boxes.

That signifies a: 07 = LT1 , 000 = custom no COMP shelf spec, 8 = cast core

If you got a cam spec sheet from CompCams that has all the specifications, then it's legit. I ordered my cam from CMS also and it took about a week and a half to get. CompCams makes up the spec sheets for the cams so it would have to be a legit custom grind. My engine builder also verified it by calling CompCams, but the weird thing is that they told him to advance the cam 8 degrees so he had to drill another notch to advance the cam. Pretty weird. We'll see how it all works out when everything is together and I get it dyno tuned.

 

It has a cam card matching the specs printed on the sticker on the box. So it's legit. Well, I'm alot happier now still wish the thing had the 242 exhaust lobe though. I'll run this one now until I get some bigger heads.

 

Being that the cams are the same price, you really shouldn’t have a complaint. You can’t hold it against CMS for putting some of their popular “custom” cams on their website.

I admit that I was also somewhat surprised when I recently ordered a custom cam. I was expecting to see some unusual (238/246 dur., 595/565 lift, 109+2 lsa) type specs, but instead they were a lot more traditional/common than I imagined. As long as it works, I really don’t care where the lobes are listed. You need to find a good vendor/tuner and trust their judgment.
