Everytime(but one) I have had a custom cam made, the specs were chosen by the cam company's tech, I just laid out the parameters of the engine and car and what I expected from it. I usually have an idea what I want before i call, but listen to what they explain about why they chose a certain lobe profile and then make a decesion. Companies I have used are 1 Comp Cams and about 15 Crower's, next one I do will be Bullet if not Crower.

The Comp Cams Extreme are also usually asymmetrical, and their latest designs were designed by the same guy (Harold Brookshire of UltraDyne fame) that did the Lunati Voodoo. I don't know about Isky's profiles.

If it was me I would call Bullet Cams, they bought all the UltraDyne grinds specs's and seem to be at the top of their game.

I'm with you, I wouldn't want an austempered core either, there record is too spotty on reliability.

 

Hello eric thanks for the info and your experience. If I would say go through comp cams and give the the specs that I want and mentioned the lunati do you think they would do it for me? I know its not normal to call a cam company to ask them to grind a competitors cam shaft spec but I have never done this before. I can't afford more then what I already paid. Do you think comp or ultradyne would be able to get me one shipped within a week by chance? It seems to me Lunati is very slow and really don't know what there doing at least on my end anyways that is how I feel. When i talk to them they act like they don't really want to help me get what I want and can't answer my questions right off the bat. O well I will do came calling tomorrow and see what I can come up with.

They shouldn`t have a problem grinding a cam to another company`s spec, cause many cam company`s copy each other or get close to one anothers specs so it shouldn`t make any difference to them. Believe me, it`s not like your "stealing" another cam company`s specs. As long as your cash is green more than likely they could care less.

 

There's something going on in this thread that will be confusing to others who read it later. Eric32, you are using the term "asymmetrical lobe design". This has to do with the way the lobe is ground from the opening to the closing side of the lobe. It is usually used to "snap" the valve open and then let it down more softly on its seat to prevent bounce.

While you may actually mean asymmetrical lobe design, I am of the opinion that what you actually mean is "dual pattern", where the exhaust lobe has more lift and duration than the intake lobe on the same cam.

Please clarify for those who will come later and read this.

 

Well first of all techinspector what I meant was as you stated I don't know all of what it means but on the lunati voodoo cams the asymmetrical design is what I read about in a article and a spokesperson from lunati stated about there voodoo cams using the asymmetrical ramp design. I pasted below from this site on camshaft term used.

(Asymmetrical - An Asymmetrical cam has opening and closing ramps that are different. These profiles are usually found on high performance cams and offer a high velocity opening and a lower velocity closing ramp in order to snap the valve open quickly and then set it back down more gently.)

I read about camshafts and other stuff in different magazine articles and the type lobe designs etc. It had nothing to do with a dual pattern design. I only know about that when reading some articles on camshafts.

As far as Fbird goes either your making fun of me on something I typed or I may have confused you, or does actual dealerships such as ford carry chevy parts? That sounds different to me but I have never bought anything from a dealership before. You guys are the expert teachers on here I am just a student learning I don't mean anything bad here so please don't take it that way. I just never had someone tell me to check out a ford garage for a chevy part.

If that is the case in easier terms if Lunati can not get my voodoo cam made for me on the billet core what I meant is if I gave the exact same specs to either isky or comp cam can that make me the same exact cam. Thats all. The only thing I want here is the lunati voodoo cam I wanted to get put on a billet steel core not a cast core.

I don't like the idea of having a cast core for a roller cam. I just don't know that much about other cam makers and what all they can make. If I sound stupid then whatever I am just learning here and I don't know what all they have to do to make a camshaft for someone.

With the different type of asymmetrical lobe design I read about on the voodoo cams I did not know if it required a different type of machining to be done on making one or not I have no idea. I hope that clears things up.
Thanks
Eric

 

Thanks Eric. I would make bet that anything Cam Grinder A can make, Cam Grinder Z can make, as long as Z is a well-known entity. Asymmetrical profiles are not voodoo (Caribbean Voodoo) .

 

LOL Techinspector thanks for the heads up. If Lunati cant get my cam made for me then I will give isky a call and see what they can do. I am wanting to get my cam with in the next couple of weeks and everything else rounded up so I can get my cam swap done by the end of next month. I don't have time to just wait and hope it comes in soon.
cheers
Eric

 

If you want to talk to the above mentioned Harold Brrokshire,aka UDHarold,here is the last info I have;
Everyone,

Now I've done it........
I am now selling ALL of my previous work from 1980 til now, and into the future.
If you want an original UltraDyne, or one of my Lunati or VooDoo cams, or one of my Custom Camshaft Rollers, or what I may be doing in the future, please give me a call.
I will be getting a new phone number by the first of January, but my home phone number is still 662-562-4933.
Most of the valve train components will be from Lunati, as they have the good Morel lifters, including micro-polished ones, and with oil holes on the faces, and the Pacalloy springs, including the BeeHives.....

If I made it, I sell it.

UDHarold

PS---New designs are being worked on.

I got my solid roller cam from Harold a few years ago and I am very happy with it.A custom grind is very close to the same price as an off the shelf grind.
Guy

 

thanks guy I will do that if I can't get anywhere else with lunati or one of the others. I just don't want to be told by lunati well we don't know when we will get the core you want. I would like to get my cam swap done by the end of july if possible.
Thanks for the info.
Eric

Guy,

I am glad that you had a good experience from Harold, as I did not-he is a really nice guy to talk to and is extremely knowledgeable, but he does NOT keep his promises-

I would agree with most here-Bullet is a good Company (most of the Employees are from the now defunct UltraDyne), or another choice could be Mike Jones (he is really good)-

Thanks guys for the help and your experiences. Well I made some phone calls and Lunati is still waiting to hear from there supplier and see if they can get that core I wanted. I also called Isky and Comp and neither one can make that for me on a billet core just the cast cores. I don't know what I will do if they can't get the core I need. Isky said that could do it on a regular non stepped nose design but I like to have the on my cam as to where I don't have to check for end play and all the other stuff that goes with it. Anyways thanks guys for all the leads so far on cam makers.
Eric

 

I am going with these guy's here, Have had several friends use them all with good results. http://www.bulletcams.com/ . And here is another good company that i have heard good things about also. http://www.cammotion.com/ .

confussed?

to the op,you said you had factory 5.7L/350 oem roller block set-up.why are you asking about a lunati cam that is retrofit and for marine use.cam in question lunati 60110 retrofit marine use according to summit and lunati sites.maybe i missed something in your post,just asking?

 

He is wanting to have a cam ground to these specs for his engine. Not the actual lunati marine cam for his engine just the same specs. JMO


Cole

 

If you go to lunati's website its not just for marine applications it's also for street engines it just says it can work for that application as well as excellent for injection systems etc. If I wanted that on a retrofit I would have it in my hands right now on a nice billet core but I need the stepped nose cam end for my setup. I originally went with a 60120 ( same as the 60110) lt1-lt4 grind cause it has the stepped nose end.

Only issue is the dowel pin is a little to long but it can be shortend and can be made to work with my engine setup. Anyways long story short Lunati said that don't have that cam core in a billet with the option for the ever wear gear to be pressed on the back. Lt 1-4 cams are the same as the oem late model roller cams except certain years came with a longer dowel pin and a hole in the center for the drive gear for the water pump I believe. I got a crane cam in my engine now but I want to go a little milder for good stop and go street manners.

marine cams

people are paying bigg for these marine cams and i know they are good for dune buggies but why a car?

 

thanks cole i was just a little confused,i have an 87 5.7L/350 oem roller and didn't understand everything.i'am still learning alot from this site and about the 2000's hotrodding.i'am still in the 80's lol.

 

Well guys I got a deal made with bullet cams and they had no problem with making a cam for me. The are not using a 8620 billet core or anything like that just a factory 1020 roller steel core which is good enough for me. I just told him i did not want a cast roller cam and now I am good to go. I gave him the specs on the lunati cam and he is going to make it similar to it but tweak it some.
Thanks guys for the leads
Eric
