I am going to do a tune up on my friends RV and I need to know what motor is in it. It's a 1978 Dodge Sportsman but the tags are completely gone. How do I know what size motor is in it? The local auto parts store can't seem to tell me.
Had a 79 Pace Arrow on a Dodge D50 chassis, the engine was a Dodge 440-3.
My manual is now gone and I cannot remember where to look on the engine to determine for sure which engine is installed. Maybe someone else has better information.
My understanding is that the -3 indicates a change in the route of the engine coolant. I think there is an extra passage for the coolant that routes the coolant through passages in the intake manifold. Therefore, the installation of another 440 intake manifold (without the passage) could cause overheating and failure of the engine.
