My cam looks like ch!t!!!!! Why??

and that wasn't a dig at anyone... there are positive reviews for all the cam distributors...

but there are also people who have had issues with them as well... was it install error? improper lube? don't know, and at this point, don't care... because I can't afford to be a guinea pig

Forrest, although camshafts are a mechanical piece and failure at some point is a pretty high probability, we have yet to see any major lobe wear since our re-design.

Just wondering where you got this cam? Do you recall what vendor?

I am asking because we have been grinding the area directly behind bearing journal number 1 at the front end of the cam for the past 3 years and this one pictured is not ground in that location.

Mostly curious and trying to keep an idea of what, when, where, who. That kinda stuff.
 
i ran a helix II for 2 1/2 years. DID NOT change tappets. Spun rod bearing and pulled the engine apart.
Sold the cam to a buddy of mine HE has been running it for about 2 years. DID NOT change the tappets.

STILL RUNNING GOOD!

I don't think I'm speaking out of school on this, I'm sure he won't mind...

But I do know he had this cam for quite a while before he got a chance to install...Approx. a year or so......I was going to do the install for him a while back but he was traveling / working so much, we could never get together at Garmon's....

I really dont remember it was in '08. I had to get the springs(tre/browns?) from one vendor and the cam from another(tre/browns) and the flux's from Source. From what I remember as far as conversation was it was the last one available at your shop for whatever vendor. Other than that everyone was out of stock. The box it shipped to me in had your p.o box Anna, tx if that helps.
 
Hey Don
Cam should have arrived Thursday. Have you had a chance to look it over?
 
The reason to install a 24 valves or CR tappet is not because of the difference in width of cam lobes, it’s the simple fact that the new cam designs with the more aggressive ramps use more of the lifter lifter.

I always tell people to use the wider tappet from the 24 valves or CR in a 12 valve. Out of 150 new cast UGL cams I’ve sold, and the 600 regrinds and 50 steel billets , I've lose one of the new cast ones in Ryan Lusk’s motor, he used a 12 valve tappet , my fault for not making sure he used a bigger tappet . The cam lasted 10 mins , this is how significant the lifter design needs to be. I have lost 3 regrinds out of over 600 , and this was more along the lines of the old tappets had wear spots on the lobe , in that there core they sent in had the same wear on the same lobe . if you cam coming out looks good , you can get by using the same lifters. You should , but we all should do a lot of stuff



This Cam lobe urban myth is just that a myth. I don’t see eye to eye with Don, but there is no problem with the width on his cams. I wished my cams were narrower, that would allow them to fit on the newer CNC grinders for one off race cams. My new 60 mm cores are narrower, and it cost more to have then machined narrower, more machining time of each core. This is a marketing ploy by the youngun.

Sure Cummins makes there lobes wider and wider, but this is more in line of casting, it’s really cheaper in the process , and why not on a motor that could become a low rpm genarator and run for ever at low rpms , meaning less oil splashed up on the cam lobe


. We use the cores we have available, some of us have ideas that we believe in, and I personally believe its all percentage gain. I’m sure that when Geoff at Colt cams the real brains behind the youngun’s whole program had his reasons, and I respect his opinion.

The rest in just that marketing.
If Don’s Cam’s had a problem as this marketing tries to imply, then on the forums, Don would have been long ago out of the cam business. People still buy his cams. I sell a lot of cams as well; I am more for the person that wants a little more than a cookie cutter cam, and is willing to work a little more, by degreeing in the cam, and checking true valve clearance.

Remember that tolerance variations in a mass produced engine, can stack in the worst possible way.
You wouldn’t buy a trick P pump and just put it in at the window , heck you run it forward , and backwards to find out how it runs best in your motor , and you particular combination of parts . If you can time a P pump, you can surly degree a cam in.



Now to oil , and additives , the new oil sucks , but it’s not all of the problems , use a good quality of oil use additives , I use TX7 from Polydyn Performance coatings by Polydyn if you look, most of the ProStock guys and Comp Eliminator guys use their coatings and additive . They will even CNC cut valve reliefs in you pistons before they coat them


The bottom line get you parts and advice from people with real experience in these areas, don’t listen to the marketing hype , and urban myths.
An old saying in the car business, “sell the sizzle, not the steak “ I added one more to part to that . “ because all steak is just dead cow” . Some people make a big deal out of little stuff, but if they had real experience, then they would sell performance

just because you did something doesn't mean it's right.. :D
 
Greg, damnit man, will you use spell check? I fat finger a key now and then but good gosh you slaughter the king's english! Cut out the narcissistic behaviour and spell a little better and it would give your argument much more validity.

I guess the cummins engineers had it all backwards. Hmm, lower zinc wider lobes, even lower zinc, even wider lobes. I am off my rocker i guess. It is the best marketing ploy ever that wide cams last. Maybe I should do more of what you and Don do and less of what engineers that make over 1 million engine per year do. Given your opinion with the narrow lobes, this cam should be running until the end of time.......

I guess you didn't get the memo about the TPS reports or the fact that Colt and Hamilton are no longer doing business together. Geoff is a very intelligent individual though, no knock there. I don't think he shares the same sentiments about you though and your double talk.

I like the term young gun,by the way. I am glad you can see I have achieved enough to be a threat to you before I need Viagra. I guess anybody under the age of you is not allowed sell cams. Remember there is no fool like an old fool. Glean from that what you may.

The same company that made 99% of the 181/210's and the OE Cummins manufacturer. Geoff typically did all of the custom grinds.

Can some one tell me if i can run the zddp, or lucas zink additive, with a synthetic oil, like amsoil?
 
I ran synthetic before cam install last year, was very happy with it, would like to go back but i wasnt sure what the cam guys recommended, but Zach, PMed me after that question and said there wasnt a problem with that...
