1978 Dodge Sportsman RV Mike Remar 6-28-08  
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.

The 440-3 in the industrial Heavy Duty 440 engine used in Marine Industrial and Heavy Vehicle applications such as Motorhomes, Busses and Big Trucks.

Re: 1978 Dodge Sportsman RV John P. Newman 6-30-08  
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.

Crawl under---look on block---it's either a 360--or 440
the vin---on the door jam will help at parts place--
Re: 1978 Dodge Sportsman RV John P. Newman 6-28-08  
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.

Good luck with the tune up,
John

I am attempting to put a water pump on.
The whole front of the engine is open including the radiator. I think all the parts are probably there but am looking for a detailed picture of the front of the engine (behind the radiator) as I have many bolts and some sleeve for bolts that probably serve as spacers etc. I didn't take it apart!

What does the 3 mean after the 440?
Thanks

Re: 1978 Dodge Sportsman RV eske 1-26-14  
I recently bought a 1978 Tioga 21ft Class C RV with a Dodge 440 motor.
(Rear bunks, front rv door)
I'm looking for any of the original literature on it - Owners Manual, Parts List, Engine Manual, etc, etc.
Unfortunately, Google hasn't yielded anything helpful and the previous owners lost their copies.
If anyone has anything, please email kayratto@gmail.com
Thanks!

My sportsman rv has the 318 v-8 in it and I'm having a hard time finding the vacume solenoid and the correct installation for it. Do you know where I can get this part and an owners manual for the rv?
Re: 1978 Dodge Sportsman RV jerry brenkmann 8-23-14  
Had an electrical problem at the start of a trip. The engine started to miss, backfire and stall. The ammeter needle was pegged to the discharge side. I shut the engine down and took a look under the hood. A red wire coming from the alternator thru the wiring harness to the fire wall was very hot(insulation melted).I let it sit a few minutes and started the RV. It ran for a time, the ammeter gauge was working again but soon it shut down altogether. I removed the harness and found burned insulation on any wire that touched the red wire from the alt. rebuilt the harness, installed it and now have lights. When I turn the key to start nothing happens. The ammeter indicates a slight discharge but no engine turnover. What am I missing? Could use a wiring schematic to trouble shoot but can't seem to find one. Any ideas out there?
Thanks, Jerry
