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?
doing research on web, these are the numbers I found,
440 All years use
Champion Copper / Spark Plug Part Number: #406 or RV12YC
Autolite-Platinum / Spark Plug Part Number: AP25
Motorcraft / Spark Plug Part Number: 450
Ac-Delco-Rapidfire / Spark Plug Part Number: 1
Autolite-Double-Plat / Spark Plug Part Number: APP25
Ac-Delco / Spark Plug Part Number: R42TS
Bosch-Copper-Super+ / Spark Plug Part Number: 7969
Autolite-Resistor / Spark Plug Part Number: 25
Motorcraft / Spark Plug Part Number: SP-450
413/361 all years use Champion part # 405
Found recommendation for RV12YC here. the other numbers are other manufacturers equivalency to the #406.
Oil Filter '60-'75 413 cart. type part # 1092
Oil filter '60-'75 spin on type part # 1515
Oil filter '74 only, 440 eng. part # 1515
Oil filter '75-79 440 eng. part # 1068
Air filter ''60-76 all engines part # 2244
Air filter '71-'76 all engines part # 2044

a Post from somewhere-
While this information is located on the first page of the Dodge Parts Book, I suspect it gets missed. Because of the
coding used in the Dodge MH Parts maual, it can be confusing at times to determine which part number you need. You not only need the year model, you need the chassis key code from the first page of the parts manual. Dodge did things like referring to the M375 chassis as M4 (If you look at the brake overhaul pictures they refer to a 72 M400; it's actually a M375).
The following table is a condensed version of the key code information.

new engine mounting brackets depending on the engine you choose. Both 318s and 360s use Dodge PN 3894712 for the right side
(440s use PN 3823214), but the left side mount is different for all three engines:
PN 4112853 for 3l8s, PN 3497409 for 360s, and PN 3823215 for 440s. The rubber insulators are the same for all
'72-'92 trucks, (except those with 3.9L V-6) PN 4088033 for both sides.
some parts numbers I've gathered from other forums people discussing 440's and Dodge RVs.
Can anyone confirm that above info is correct?
