It looks like they have been through three owners and each time the catalog has been pared down. you are correct, on the list of available cams.
The cam that I have is for a 6 cyl. It is still in the original box with the matching lifters (I assume). The box is well worn, but the cam and lifters have never been installed. It has a center distributor gear position. I hope to find some info on this cam.
