This is for 340 builders

The rods I have are pressed in.
You are right about the 340 pin diameter.
I was always building big blocks. But the 69 Dart I did with my son turned me into a firm beliver that the 340 is one of the best small block to build.
Hind sight is 20/20. Most people did give them away. Everyone coulsd afford to build big blocks. But to keep a street car a sleeper, 340 is the way to go.
