This is pretty tempting bait for a geek like myself.
Thanks alot buddy!
Left to right...I see A very wide front bearing journal, a seldom used fuel pump lobe, then a distributor drive gear.
It really looks just like the handful of big block Mopar roller cams I've worked with.
But wait!
Check out the first lobe after the distributor drive gear.....could it be an exhaust lobe (as on a wedge)
Or
Could it be an intake lobe (as on a 426 Hemi)?
Judging from the arrangement of the lobes as shown
behind the second and fourth journal, and assuming the direction of rotation is clockwise
as it would normally be, I'm going to to way out on a limb and take a wild guess
that the first lobe behind the distributor drive gear is an intake lobe.
If that is true and it's actually an intake lobe behind the distributor gear, and knowing what you would
normally collect parts for....then I believe you're looking
at a 426 hemi camshaft with the xr292r-10 grind, same grind commonly used among different brands.
Shouldn't it have a grooved 4th journal? I guess a customer could order it either way, with timed oiling or full time,
although with a World block you have no choice/doesn't matter. I believe this grind and layout was
used at one time on Indy crate engines and it may have been pulled from one.

Another thing that is noticeable is, in front of the 4th bearing journal, the lobes for #6 have basically the
same placement as the lobes for #1. This means the cam does not have 4-6 firing order swap.
Rich,if it's laying in my garage,,,,,,what did it come out of?? A HEMI of course.After I find the specs it wil be up for sale,,,,,,hint,hint 
HEMI-ITIS has no cure.
