I just returned home, saw all these newer posts. It's a little late to look up the number on the crankshaft, sorry.
Have we reached some sort of conclusion yet? It is still a little unclear to me. Does HAA mean 1950, or does 3701946 mean 1953? Do either of these numbers exclude hydralic lifters?
Does someone still want to see some other block numbers?
When adjusting for hydralic lifters, one follows the same procedure but tightens each rocker so that there is no gap at all? What about the spongy movement? One leaves no gap plus this amount of spongy movement.
I read up on your blog, Dave, but I will need to study it a bunch more before I start to understand hydralic lifters.
I sort of prefer the mechanical adjustment, it seems more straight-forward.
