How can I tell which model of O-320 that I have?

look at the data plate....on the top of the engine.

It'll probably be down on the oil pan/intake in this case.

First post....

Welcome to POA.... :cheers:

As for your question.. We can narrow it down alot by just knowing what kind of plane it is in..

Probably the easiest way to find out, much easier than uncowling the engine.

Your plane originally HAD an O-320-A2A or A2B. Only you can tell what is currently HAS, by looking at the data plate on the engine.
