Inliners International Forums General Discussion Hi Performance 250 Roller cam

Does anybody know where to get a roller cam? New, used or just the billet core would be fine.
Thanks

If you find a used one, they are most likely high lift high duration w/a tight lobe center.

Not sure what type of specs you are looking for??

Last I heard, nobody is making any.
No cores available either.

There are companys that might make you a one off cam, but that will cost you about $1000.00 or so?

Might have better luck getting one from Brazil??

Douglas,,, what do you think?

MBHD
Goodluck!

Crower lists solid rollers for Chev inlines in their catalog. They are made to order and they also show they have 292 cores available.

Never heard about something like that in Brazil. All the cars I know with roller cam have north american kits. Crane by order or Crower, by order as well.
People in Brazil still using the solid lifters and cam.

Listing them & actually calling them to see if they have them in stock are two different senarios.
I suggest calling them to actually see if they have them,,,, like I said before, nobody has them in stock.
And if they are made to order try & get a quote from them.
There are people that answer phone calls & emails at these companies & will tell you they have them in stock or can get them,, but in fact they do not have them & cannot get them.
But go ahead and try, can't hurt.

Also as stated earlier, if you have the cash/credit card, someone will make you one if you have a minimun of $1000.00 -$2000.00

I called crower today and they don't have anything but could probably make one for about $1000 but they really dont even want to get involved with it.

What type of cam/Profile are you looking for.
ex. Lift,duration, Lobe sep. I may?? have something for you.

And what about the lifters? Can it be used with the roller big block pieces? How they'll be fixed together?

MBHD and 64Chevelle!

Here in Brazil we don´t have roller cam manufacturers... Only solid cams, and they aren´t good!!!

I bought my roller cam at CompCams! It´s a special order one, and I payed a thousand bucks on a Billet high lift roller cam for drag race only. It takes more than 4 months to get done...

I know here in Brazil only 2 guys using Billet roller Camshafts on their racing cars!!

PS: HANK... Do you received a few e-mails from me?? I need to talk to you!!! Please, check it out!!

I am looking for just about anything. Im looking at building a whole different engine and if I can find a cam I will build the engine around that.
On the lifters I believe that those are still pretty available. The lifter itself is still the same as a small block but the link bar is different. I think crower and crane still make those.

Well then I take it you are after all Out racing then??

No I am not for all out racing on this one quite yet. I still would like to be able to take it out on the street once in a while. Of the profiles that I have seen it looks like most of the rollers are around a 7 to an 8 hundred lift. RPM wise I would like to spin somewhere around 7 to 7500.

What kind of stuff do you have Larry? I'm intrested in a roller cam as well.

I'm also searching for old school throtlle bodies. I've seen it once, but can't remember where. They looks like old carbs. Does anyone know about where can I buy it?

I know a roller offers a little more HP but you can do the same rpms with a flat tappet.for less money and Not have to get into the 7-8 lift cams.
Mine used to Buzz 7-8000 with the old cam I ran for a long time and it only had a 583/607 lift
rpm band was 38-7200 rpm.(And used to also be my daily driver but it didn't like the stock 3.08s below 45mph in 4th gear) The New cam I know have put into this new motor is Just shy of 700 lift
which is a 680/691 lift.
But the rollers are from 712-850 Lift so these are Not even close to being street able. As for
roller lifters They Have to L6 rollers.Because The tie bars are not interchange able. The L6 rollers have one bar that is a fixed bar on one and sloted on the other.

Larry has a very informative web site. Check it out.

Thanks Drew

Is there too much diference on the rpm growth when using a roller cam? I mean in comparison with the solid one.

Roller cam essentially means reliability, not necessarily more RPM's. NASCAR folks buzz their engines above 9000+ RPM on flat tappets. For a V-thing, current cost/benefit ratio is favorable towards a roller cam, while it's almost prohibitive for our beloved inlines...

PS.: It's worth to mention that NASCAR's flat tappets have nothing in common with off-the-shelf counterparts...

I'm not talking about maximum RPM, i'm talking about the motor response. Almost like throttle response, but on the cam. You know? If the roller cam makes real diference in the rpm growth. If it help on this growth or not really.

Roller cam allows a much more aggressive lobe profile, even if you compare against the same advertised duration (meaning “more area under the curve”), which tents to result in more power (specially in higher RPM’s). However, this tends to soften throttle response, since the motor won’t have the same “pick up and go” in lower RPM’s, which is essential for those prioritizing crisp throttle response.

Now, if you are looking for a neck breaking throttle response, nothing beats a well tuned fuel injection (constant flow or electronic). If you are, however, addicted to carbs, three IDF or DCOE Webers would be somewhat close.

PS.: But remember, “carbs” are not good for your body!

A little late but...

Try calling Compcans! they have available billet cores and are accepting orders! (all custom)!

Edy,,,,
are you sure about Compcams having cores available?
Sometimes ,,like I said before, vendors/companies over the phone will tell you they have it,with out even checking stock,, when in fact they do not.
If they have them in stock I will be really surprized.

MBHD

Yes Hank, Edy already knows that Comp Cams has this cam billet or at least will make a billet. It's just a piece of steel round stock. I'm helping Edy get one made up.

Randy S. Hager

Randy S. Hager,,, do you work @ Comp cams?

It it easy to just get a billet piece.
The expensive part is to have the distributer drive gear machined.

BTW,,, how much is the cam Edy is getting?
AND,,,,,, how many are available???

MBHD

Hank: No I do not work for Comp Cams. We are dealing with Flatlander Racing. We are talking with the sales people to see if these are still available and how much. The billet is $679.00. I have not had time to inquire as to the price and time to grind the billet. As far as the distributor drive gear, that is the same as the SBC so it can be added (cut/hobbed) to the cam without too much trouble. I don't think they would do the cast iron gear on that billet. WAY TOO MUCH TROUBLE.

I have gotten the same responses from other companies, stated, sure they have the billet cam, wait for a month, because they tell me they are waiting for the cores, well, in short, nobody has the cores, they did not have any comming in & they do not know if they will ever get them in.
Goodluck on your search!!!
BTW, I do not think the distributer drive gear is the same as a SBC.
They are the same as the iron duke motor 153, or the Pontiac Fiero 4 cylinder.

MBHD

Hank, Ya might be right. I'll email the guy from Flatlander racings and grill him on ACTUAL availablity of the cam fully ground. I'll get with you if it's really available.

When we spoke with comp about the cam/Cores/Blanks Yeah they said they had some. BUT we never did get a answer as to how Long it was going to get it.And we're still waiting. SO i realy wounder.

If they are 750-800$$$ sounds like they do not even have the cores in stock.
Sounds like they are getting a billet core from somewhere then they jack the price up.

With that price you can get probably most cam companyies to make you one off cams.

Telling you they are one off cams to me sounds like they do not even have cores????

I was told, the only big enough company to order large quantity of billet cores is Crane cams?? ,& whoever needs a billet core,, they buy it through Crane,, if memory serves me correctly.

So Randy, did you grill them (Flatlander racings )on when they can get the cam & will it be $679.00?

I was thinking of grinding a nitrous cam for mine a while back. M. Kirby told me that the cores wasn't the problem it was cutting the gear for the dist. The tooling for hobbing the gear has gotten hard to come by.

A few things nobody has mention here is all the other valve train needed for a roller. .100 longer valve stems and the big 3/8 push rods that need a ton of clearance. The two peice push rods is a pain also. The rocker studs need to have stout valve girdle or Jesel valve train. So the core is only the begining to all the fun!

Steven

Guy's:
Here is what I got from the tech dept at Comp Cams.

Randy,
I do have the round lobe cores which I can put whatever lobe and any lobe sep that you desire. We do these type things regularly so it's no big deal. The down side is time and $. To do a round lobe cam normally takes 6-8 weeks after entering the order. These type cams will cost you between $750-$800 each and will have to get money for them before we start as they are a one-off type cam. I would also need confirmation of the grind that you want.

Let me know if I can help.
J.Fry [jfry@compcams.com]

Cool Randy!!

Could you ask Comp Cams if they could just sell you a core, & maybe a price?

Thanks

MBHD

Hi all:
I'm about ready to send for Edy's cam at Comp Cams. I'll let all know how it turns out.

Hank: I'll ask about just a billet and it's price. Send an email to Flatlander Racing to see if they really can get just the billet.(#61-000-0 billet) I'd like to get one cut as a Hydraulic roller with say a good torque grind for the 4.3LV6. Wonder how that would do in the inline 6? Maybe a little larger profile for the inline!

Hank

you can also talk to Ben at ben@importparts.com, some time ago he made a quoting, and he said he can get the core!
