There are two different setups for the Y-Block camshaft retention. The ’54 and into mid ’56 used two spacers and a fuel pump counterbalance and from ’57 on, it was a combination of three different spacers without the fuel pump counterbalance.  The fuel pump counterbalance is keyed and goes between the gear and the fuel pump lobe.  The later model engines simply had a keyed spacer that went between the gear and the fuel pump lobe.  It’s important that the various spacers go in the correct positions.  Here are some past threads that may help.

Ok thank you.

There is either a spacer or the counterweight.  If you removed and have a spacer, then I am sure it didn't have a counterweight.

Are you sure it doesn't have one cause the manual
For 61-63 show it. I just don't want to put it back together if it needs to be there. I have the eccentric spacer is that what you are talking about the offset piece with the washer/spacer

You probably did not remove one from a '63 292 but you should have a spacer that takes it's place.

Does anyone know where I can get the camshaft eccentric counterweight for a 1963 292? I don't remember taking one off and if I did I can't find it. Any help
Would be appreciated
