Just talked to Dave @ Hughes...

Just so I'm clear yellow rose, you're stating companies that regrind stock cores are
ALL copying other grinders profiles that use blank cores? And before you even turn the
key on an engine w/a regrind, wouldn't you have detected the variation when setting up
the cam, degree-wise,lift-wise,& duration at the usual check points?
I have only dealt w/ Lunati,Crane,Comp,Mopar,& Cam Dynamics, as well as some
generic "bargain" cams(cust's mista--er choice.... one of which wouldn't idle"JCW"lol).
So I guess other than reducing the base circle,which many cams do,what prevents these
grinders from using proprietary profiles? Or is it just certain grinders that you've already
referenced, since OC was kind of tapped by DD for a number of slanty cams,doubtful if
those were copied from ?????
Since it sounds like you've spent capitol and sweat on this I guess I'm looking for
clarification and insight.Copying copies would fall under the accumulation of error effect,
which is well known in many fields.

It's not bashing when it is FACT. Have you any personal experience with reground cams? I have. They are JUNK. It is that simple. One friend has a Predator with an OC in it. Yes, it's down on power, even though it is a DIRECT copy of a cam that worked. It's down 60-65 HP. And it's not just Oregon Cams. It's Delta and several other I have had the "pleasure" of making a garden stake out of.

I'd never know about power loss with a reground cam because I'll never purchase on.

I am outspoken. Because it's stoopid to stand back and watch people blow money and not feel bad about it. You can't say wrong is wrong? That's on YOU.

No no no, just saying, just saying....

I haven't bashed anyone. I ran jpar down because he trolled me. I gave him 100% sound advice and he argued with me, because he didn't like they way I said it. Boo Hoo. So I stay away from him. Until he trolls me.

Telling the truth over and over again while following him around is bashing but, like I said, I'm just saying.... just sayin...

You should probably rethink your posts. You are another one who doesn't do this for a living. Just a hobby guy who wants to be a hero. But when you have to charge some one big money to fix stuff they did because they took the advice from the internet, and you hear all the bitching and whining about how much it costs to do things these days, or better yet, stand back and look at all the broke *** people who go without and spend and spend and spend and never learn. I'm tired of it.

Yea, I get that once in a while from some thin skinned babies. I used to do this for a living. Wraped it up for something different. Now I'm a hobby guy. I'll be a hero if someone thinks it of me, but, I'll shun the title. Each and every time. YOU think I'M a hero? No thanks...
Don't get tired of it, profit from it!
I used to make some dang good money from the exact example you gave.
I used to love & hate the net for that very reason!

So I will continue to correct errors in the hopes that one or two people will learn. And the best place to start is NOT USING REGROUND CAMS unless you can't get something else.

ALLWAYS but ALLLWAYS get a new /unused cam! Thats my advice!!!

And for certain, correct away! IF I'm wrong, just say, Hey rumble, I think your wrong or I know this is the way it works. Tell me your been there done that story. PLEASE! This is a better way to "Internet teach." It also works well inreal life. Been there, done that, still doing that. It's on the job training."

Trust me when I tell you, were closer to being a bird of a feather than you might think.

I have never even thought about a regrind ?
I figure there are enough good cam grinders I have no need to ?
I have also used both the mopar 284/484 cam and the 292/508 cam and they seemed alright to me ?
I'm sure there is better but they seemed to work for me ?
With all that said I think there are quite a few know it alls on this site that are full of it !!!
A large amount of duche bags !!!

Lastly some really awesome car guys whom I respect their opinion and input !!!
Thank you guys !!!!
Thanks forabodies only !!!

Well I had posted it once, but the mod decided to delete the whole post so once more, for clarity, I will post once more.

I don't know ANY cam REGRINDER that actually designs, develops and creates a cam lobe. They take know cams and COPY the existing lobe. When a cam is made, someone makes a MASTER lobe, and ALL successive lobes are made from the MASTER. A cam REGRINDER makes a MASTER from an EXISTING lobe, so they are making a copy from a copy. Does that make sense? It is almost IMPOSSIBLE to copy a lobe. That's why cam MANUFACTURERS make a MASTER to grind from.

I tried at length to copy a cam. I was paying $115.00 (my cost) for a cam I had use often, liked, and was going to use over and over and over. I could get a reground cam for $55.00 (my cost)! So why not do it? Because they were JUNK.JUNK.JUNK. Down on power. Every time. So, we decided to put them on new cores for 20 bucks more (we started out using used cores and thought the issue may be that and I'd still be saving money) and the result was the exact same. Every time I used the reground cam (on a used core) or the copy (on a new core) the results were the same. I can't how many times I had to pull the reground cam out on the dyno and replace it with the original and EVERY time it picked the power up. I will tell you we were trying to copy a Clay Smith grind. I can't tell you how much money I have wasted with this crap. That's why I'm saying not to do it.

Let's see if anyone learns. You can't copy a lobe and expect it to work. I don't care who the regrinder is.

There is a place for reground cams. Absolutely dead stock stuff (and then it can still be problematic) or when you can't get a replacement. But the fact is that almost all cam manufacturers can regrind FROM A MASTER, not a copy of a master.

Why even bother?

 

[rumblefish360]

ALLWAYS but ALLLWAYS get a new /unused cam! Thats my advice!!!

And most inside the engine parts if possible. But, do what you wish. It's amazing how much some guys will try and cheap out on a rebuild or wine about the cost of something.

 

[Cudafever]

If i had installed a cam and you didn't like it, in the way you don't like j par cam. I would take your opinion into consideration.
BUT I would Not pull out a cam, that i liked the performance, because you say i left some power on the table!

I haven't had any problems with j par posts or threads. just saying................

I should not say this because I will be considered a troll and all that. Last nite some one from FABO sent me a video of jpar's car making a pass at WDS. I watched that vid a dozen times. Somewhere in the thread he says he wants a 11.2-11.3 car and he is running 11.7 now. If he didn't change a single engine part, not one, I could get him there. I would send back the superstock springs he wasted money on, make him fix the clutch and teach him to tune his suspension and shocks. That would get him where he wants to be.

But you can't use shocks on the front with all the oil removed (it's not 1977 any more), he has too much tire, WAY too much clutch and it looks like not enough gear. I don't know if it's a first gear issue or an overall issue. If he just fixed what he has, he would be where he wants to be.

But he thinks I should beg him to let me help him. That will NEVER happen. Sad to say, in 1979 I was him. Doing it the hard way. With a stick. And no help. Lots of guys running their mouth but no one ever ran a stick.

what are the specs of the camshaft you are getting from Hughes.
I have a Hughes solid in my 383, a nasty grind to replace the 557.
