Greetings,
I have a 1957 Thunderbird 6T. It has the "Ramp Cams". The Cam
gears themselves have not a timing mark 1 on them! The center gear has
all the marks on it as does the crank gear. As the engine came to me already disassembled I have no way of telling what is what. None of the
manuals I have make mention of cam gears with no timing marks. I
know from past experience some industrial engines use the key way
as a starting timing mark. I do not feel this is the case here though.
Can anyone shed some light on this for me??????

They do unless their wore off.

Thanks for the response. Your pictures are the ones I have also. There
are no pictures of cam ends showing key way location. My gears show no wear. They appear to never had any marks at all. That is why I need a picture of a cam showing an end view, that way I could see the relationship of the key way to the cam gear timing mark. Please this
is driving me up the wall!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Thanks and Happy New Year, Siccatt

If you have this book you must know the cams are in the right position as represented in the picture.
