Need two used engines
 

My flight instructor has a 72' 337F that needs two engines. He is looking for mid time engines non-turbo. He said ones from 65' to 72' bird would work. Any help would be appreciated. Thanks in advance.

I guess he had already rebuilt them once. They are normally asperated.

Huh... what happened to the old ones...
 

Was this a turbo before... is it normal asperated??? what happened to the old engines... and why can't they be overhauled... ???? GMAs
