Do you have the number of the Crane handy? I haven't been on their website lately but after they got bought out their cataloging left a lot to be desired.
I should be taking off to work but you sparked my curiosity. I see Summit has some Crane products and they have 3 or 4 small block cams with the same profiles. If I can, I'll list them from mild to wild! (not really wild but getting into stall converter and rear gear upgrade territory) The last one listed is the one you mentioned Rumble.
