that's great compression

Yes that can be a good compression for Dodge Mitsubishi. But tell me where you are looking for this used engine. If you haven’t bought it yet, then I can suggest you one good place called http://www.buyusedengine.com/used_engine.php?make=Dodge where you can get even better compression ratio in used engine for this car. Compression ratio should be higher as it is very advantageous that permits an engine to extract high mechanical energy and allow the same ignition heat to be attained with less fuel.
