I had forgotten to check the timing, I'll check it tomorrow. What should it be? I'll be sure to listen for any pinging too.

440 All years use
Champion Copper / Spark Plug Part Number: #406 or RV12YC
This is what I picked up and installed today. The parts store didn't have any RV9YCs, and the guy said he hadn't seen that cold of a plug in a while. He was familiar with the confusing situation, and found the RV12YC listed for use in all motorhome 440s. I figure the previous owner had changed to a colder heat range for some reason. I'll pull them and check them after some miles to see how they look. So our rig now has a new cap, rotor, and plugs and it runs great. Now just to see if it will pass smog.

I'm curious to see pics of the inside, the window set up on yours looks almost identical to mine, I wonder if we have the same floor plan.
Here are some pics of the interior from when we first got it. It's a mess, at this point all we had done is install new blinds. I'll post some more later, we've now installed new carpet.

I have a 1977 Dodge Journey motorhome with a 440-3 engine. My owner's manual lists the RBL9Y as the proper plug for this engine. Unfortunately, many auto places no longer carry this plug. Many do not even have a listing in their books. The champion RV12YC is an equivalent plug that can be used. I've used it in my motorhome for the last 15 years. I'm very happy with the performance and upon replacement I notice the colour of the plug is within the proper specifications.

I found a booklet with these specifications for the 1977 440-3 motor...
Spark Plug Gap and Number: .035" (0.9mm)
Champion: BL9Y
Resistor Type: RBL9Y

I figured that a build date of 12-78 would be a '79 model year (didn't the model years usually change around Sep?), especially since it has the 4 headlights. Maybe the chassis is a '79, and the engine is a '78. But according to the Champion apps list I've seen, the RJ12YCs are for a '78. But they are so different than what was in there. I'm inclined to just go get some new RV9YCs, but I'd like to get to the bottom of the application questions. When did the 440-3 cease production? Isn't '79 one of the last years? Where do I find identifying numbers on the engine and/or heads?
