I have an O-320-E2A core for my -9A project. It is a 150 HP engine with 7:1 compression ratio.
My plan is to change the cylinder assemblies to 8.5:1 compression ratios during the overhaul. After looking at the Lycoming Parts Catalogs, I think this changes the engine configuration from O-320-E2A to O-320-D2A.
In this case, how does one change the data plate? The current one is pretty old / faded. I imagine at a minimum I'd want to change the engine model number and HP rating.
In a related question (maybe for Mel?) - the engine model number defines the accessories too (magetos, fuel system, etc.). If I want to change those as well what do I do with the data plate in that case?
I might even choose to put an experimental magneto or fuel injection system on. In that case there is no Lycoming part number that is correct. What have others done?
