Hi Folks: First, let me say thanks to all you guys who offered to assist me in identifying the correct part # for the cam shaft in my 300 F. I was able to clean most of the "gunk" off the alleged original cam that was given to me in a box of "parts" by the previous owner. The following is what I have been able to decipher from the shaft itself: 3D28 D3 2129804 The consensous of opinions from the list members was the correct part # as described in the 1960 Parts Catalog is #2129203. The previous owner just recently advised me that when the engine was rebuilt in 1998, they used a cam shaft out of a junked New Yorker 413 since they could not locate a specific cam for the 300. I do not have any paperwork from the rebuilder which would indicate the part # for the cam he installed. So, now the question is, do I believe the part # supplied by the members or the part # I just discovered on the cam which is supposed to be the original? I am open to advice guys. Thanks, Tom Harkins 300s4ever [Non-text portions of this message have been removed]
