Hi all, can anyone provide information on the following stamped number on the end of a small block Mopar hydraulic camshaft I have:
RPD20
B1 7
I think it's a Mellings camshaft, but I can't find any more information on line. It was in my 273 Commando motor, and it had low vacuum at idle and sounded very lumpy. So I'm thinking it had a ton of duration and wasn't any good for my little 273. Any specific information would be appreciated. Thanks.
