73 Dodge Motorhome
I got a 73 Dodge motorhome and not sure what engine is in it. It's a van nose class c I think they are called. Any idea what motors come in them? And if a 440 would fit?

Yes you should be able to put a big block in there.
As far as what it has it could be anything from a 318 to a 440.
There should be numbers cast in the block on the drivers side under the head behind the motor mount that will tell you what you have.

A small block, 318, 360, will have the dizzy in the rear, a BB will have it in the front.... just a thought......

They did make two versions of the 440, an industrial as well as what they put in cars/light trucks. I know for sure the exhaust manifolds are not interchangable between them. Got a 76 Superior with a 440, but the plant was replaced before we got it, and need to find out which one we have.

Mark you also want to look at the Frame past the Rear axles and Re inforce for towing.
I have a 76 Dodge with a 440.

So you have a 440 in a dodge van type motorhome?

Mine is a short motorhome so I don't know how much has been added to the rear section of the frame. But I will look into it when I make a hitch for towing the car trailer and truck...

early ones had a 413ci as said before on the side of the block, they are cast in what they are, by the freeze plugs, :lol8:
i didnt pat attention, but being a van nose, should be a 318 ?

Got a chance to look at it today and nfound it has a 360 motor.

The rear frame past the rear spring shackles is very short. Don't think it will need much other than a good hitch, the one on there is home made and by the looks of the material a farmer using his old wore out blades...

that was why I said to look at it and re=enforce the Bolted on Rear section. My brother made a great hitch on his class A..... then bent the frame pulling his son's FS Bronco. Most Hitches you find on older MH's are Home made from what my RV Friends say they were only intended to flat tow...
