Blank cam core?

[build it]

Does anyone have a source for blank cam cores?

Id say S&S or Andrews.

I talked with Andrews at the V-twin Expo., and they said they can & will build you anything you want, in either gear drive or chain.  Come to think about it, I need to call them!

I only need the core though, maybe two or three.

Are you looking for something over 650 lift?
The 510- 650 cams are pretty well covered . You can find at least 3-4 versions of anything you need. 
650 up lift . You might turn over a new stone .
If your looking for something over 700 lift ? I would call Jim Leinweber.

You know, I'm not sure where lift will end up; for obvious reasons I'd like to keep lift and valve jerk down if at all possible. I did assume that what could be done =<650 wasn't exhausted as no one had a specific recommendation in my other thread.

Gear drive or chain drive?  I'll ask them when I call...

Thanks K, gears for this guy.

I believe that Andrews machines all their cams from billet material not forged blanks.  The heat treat process is critical for billet cams.

Interesting, how complicated of a process is it to have billets heat treated? Do you know of anyone that has forged cores?

[NCTURBOS]

When I spoke with them at the Expo. they said only the chain cams need to be sent out for heat treating.  We didn't discuss this in detail, it only came up because I asked about lead time to get some done and they said the gear drives can be done much quicker because they didn't need to be sent out for the heat treating.

Not sure I understand this..  While you might get away with soft cam lobes and outer journal. The inner journal runs on the needles  would need to be bearing race hard. Do they press on a sleeve? The only difference between gear and sprocket cams is the sprockets.. I'd figure the steel for roller chains would be OK but if they were silent chains they might need a hard face.. (?)

Max...  We didn't get into detail, but I believe it's because of the gear drives being made out of a different material, and therefore not needing the heat treatment that the chain drives require.  I'll have a call into Gary Wallace at Andrews later today, and ask him more then.

They must be doing heat treating in their own facility as there is no way in hell the lobes would stand up agains bearing grade roller on the lifters.  They are probaly doing e-beam HT on the lobes and bearing surface. 

[NCTURBOS]

I left a voice message for Gary about 30-min. ago...  IIRC, he mentioned they outsource the heat treating, and that is the reason a custom chain drive takes longer than a custom gear drive.

  Build it is looking for just cores to have ground by someone other than the usual sources,those B2 heads are going to require something a bit different
