Yes, since everything I have is aftermarket from the block to the tubes, dipstick and pan, I just don't trust the dipstick. I guess that's the whole point of the original question. It's tempting to put in an extra quart based on the fact that it was done in '67. However, I'm assuming there is probably a reason why that was stopped. So I think what I'll do is just fill with my 6+ qts and mark that on my stick as the full level.

I did find this information which my take on it was follow the manufacturer's specification. No real surprise there. But I did learn a little bit more about windage.
