Identifying an Isky Cam

Anyone out there with an old Isky Cams Catalog, I bought an Isky cam on ebay, the seller listed it for an early Dodge tall deck Hemi 315-325 cu, when I compare it to a stock 325 hemi cam some of the lobe angles are off, here's the information I have, metal tag # on the cam is 31577, the grind is D-410, it also has crossflow & hyperbolic stamped on the end.

Thanks for any help. Lynn

PS I've sent two e-mails to Isky tech department & they never bothered to reply.

I bet these guys could help you out:
