CAM ID help please

Update:

 

Added this pic but not much more to go on here!

 

 

 

 

 

I have come a cross this cam shaft, I have no history on this other than it is back from the 80's. The number listed does not come up on any of the searches I have tried.

 

I know its not much to go but I am hopeful someone has come across one similar. Any input would be much appreciated.....thx Mike

Those are casting numbers and might lead to the manufacturer but probably not to the grind of the shaft, any markings on the nose where the cam gear bolts on most grinders put the id marks there.

What is the minimum and maximum dimensions of one of the cam lobes?  As Marty's son mentioned, are there any stamps on the nose?

I am curious as to what it ends up being.  The lobes look to be in fantastic shape, it does not appear to be a regrind.

...and those bumps are taller and fatter than most, too.

 

In for pix of the nose of it!

well, huh- it's a 'made' cam- I'm curious now who made it!

 

the ground face of the flange is different-most are simply turned.  The cast-in

'key' is interesting...

only thing for it now is to install it in a head and degree it...

Stamp looks like an 'S' in a circle and triangle. Schnitzer?

I see an "R"- but can't dredge any old cam manufacturers beginning with R out of my brain.
