Depending on the age of the 320 and whether or not the valves are suitable for running on Mogas it mightn't be that costly a conversion, since it's basically down to compression ratio, and changing it possibly through substituting different head gaskets.......but!
However there is much more to be considered if your want to get this engine certified........and that's where the picture chages considerably.
