ArchiveWhat do these engine configuration numbers mean?Dear MikeI recently bought an engine and I'm confused about the configuration numbers. Say you have a IO 320 A1A does this engine come with several different types of case configurations i.e. Dynafocal 1 dynafocal 2 or did Lycoming just build this one way. I thought that the numbers were there to keep the different configurations from being confused.
Or am I wrong? Are there 3 or 4 different types of IO 320 A1A?ChrisChris:Lycoming has done some interesting things with their manufacturing methods corresponding to part numbers and model numbers. (The biggest place the confusion comes from is actually in the cylinder flange configuration.) Unless the subject engine has been field modified, your question concerning engine mount configuration can be answered as follows.I trust the engine you purchased is the IO-320-A1A, because this answer can only be applied to this specific model.

I'll also trust you purchased this engine for a homebuilt, and now you need to buy / build the mount to attach to your airframe.
