I will be searching a few other places but wanted to ask. The 403 motor i have in my olds was rebuild by the previous owner and he put in a cam he purchased from the Oldsmobile Performance catalog from the 90's. He said it was an Olds Marine Cam that was discontinued. I know its hydraulic and not a roller cam. I'm in the process of trying to find out what cam is in this motor. My hope is someone out there on the wild wild web has said catalog and will be generous enough to post some pictures of the pages with the cams on them in this post. Any help is appreciated.
