To find what cast number is on rocker arm.


Hi thanks alot for the help. Did not realize the rocker assembly was in 2 pieces, and this will be a good time to clean the whole assembly.



Pretty sure its an intake rocker: http://1954advance-design.com/Web%20images/1958-60-rocker-oil/1958-1.jpg

Then according to this the number 2 cylinder intake valve requires a LH Rocker cast #5, part number 839563.



I guess the search begins. Should I post a wanted ad looking for a #5 rocker for a 216 engine? Or should I just buy a complete rocker assembly?

Thanks all!

-Funny, when I search that part number it is giving me a 216 flywheel...
