BBC Crane roller cam ID

Hi Boys,
I got a crane roller BBC part no. 139536 ,trying to get the settings and specs. Crane is out of biz, by a couple my old books it's late 80's early 90's because my circle track no.s are close , any body got a crane cat around then , Thanks Dave

 

If you have a block, crank, timing set and lifter, you can check the specs yourself with a degree wheel and dial indicator. Start with the lash at 0.025", tighten or loosen from there.

 

I looked in all my crane books i go back to 76 i can't find that number.

 

Could be a custom grind that won't show in a catalog.

 

Then it would have the lobe ID,s etched in the cam
something like R-274/280
I have a Crane Cam Master lobe list catalog if it has the etchings it may or may not have them as there is no date on this.
