Need Help to Identify Crane Cam for Briggs 5 HP

I'm hoping there a few "old school" racers out there that remember something about the Crane Cams for the Raptor engines. I recently purchased two NOS Crane Cams 91012 & 91016. I have the Spec Sheets, but they say nothing about the RPM (power curve) for these cams. Crane Tech Support couldn't provide them to me.

Does anyone know what the RPM Range are for these two cams ?

I'm in the process of building a "clone" Raptor 3 and would like to use one of these cams.

Any help would be appreciated !
