rocker changes
 

Does anybody know when the rockers were changed from
the cast no-bush type to the bushed type with the boss
at the oiling holes?

I've looked through Anderson and it shows the different
types of rocker arm but I can't find the text for which year
this change was made.

I was taking apart a 68L and half the rockers were non bushing and earlier in the week I disassembled a69 E and it was all bushed rockers.

Did they have the boss around the oil holes? If not they were cast rockers
which had been bushed.

Ill have to look because I would put them on the shelf of things I would never use if I build. The customer would have to say that he wants exact period engine and I would still try to dissuade him..much like the cam carriers with just 6 oiler holes instead of 9..why use them.

FWIW, my original '69 T had rocker arms without bushings. When I rebuilt it, I had the machine shop install bronze bushings.
