Wayne,
I have my engine (2,2) down to the connecting rods. I read in your book about keeping the wrist pins with the same pistons. That makes sense but you also mentioned mix and matching them with pistons to do a little low budget balancing. Were you talking about new parts or the old parts?
The fact that the wrist pins have already been pressed in would make be think that they should stay with the same pistons.
But then given the superior German engineering that was put into these engines make me think the tolerances would be quite tight.
Cast iron cylinders- besides honing them what else do you suggest? The cross-hatching is till visible with very little carbon build up.
