Cap anyone tell me which cap is correct for a 1965 283 (Acadian) 1. has oil and AC on top 2. has oil and oil on top 3. has oil and oil and 2 indentations on top.
I have seen all 3 but am trying to get correct for my 65 canso SD
And the worst of it is, the current GM replacement is none of the above. It is totally smooth, and bigger diameter.
This is a pic from a 65 327 I have had for about 25 years. I am assuming it's original, but no guarantees. I would think this is #1 on your list above.

So your's has.... oil, ac and dimples. That would be a fourth (fifth with the smooth) different one. I have also heard the nova/chevy 2 were different from acadian (again!)
