I will go probably just go down to my local NAPA then for the parts. Finally starting to act like spring so I can get back to work on this rig. Not into working in the cold when I don't have to.
I don't think anyones dying statement ever contained the words "I wish I had spent more time in the office", so lets go somewhere!

What I do find is that there is a California emissions vacuum hose routing sticker (very large) under the hood. Checked and found everything correct per this sticker but I haven't found the charcoal canister (yet). Now being that it was originally shipped to Calif. it may have just been Dodge's CYA since that is where it was assembled.
According to the old Motors manual I have available their are no "CA equipped" -3 motors. The only thing shipped for sale in Calif was the -1 equipped 220hp hypo police interceptor motor in the MB400 cutaway chassis. The plugs are the main difference and that's one of the things that may have to be changed given that -1 motor plugs "may" be hotter hence my dilemma the 2 plugs listed for the 440 are Champion OBL9Y (440-3) OJ11Y (440-1). I may have the original sale paperwork in the RV that may tell me where it was first sold, but it's late and I'm too tired to go out and look for it.

Look under the drivers side sun visor for a sticker that has all the information on your Dodge MH. It will tell you engine type, etc.
At least on my Dodge MH there's a sticker located in that location.
1. Try advancing the timing a few degrees. (More BTDC) If your engine 'pings' under load (acceleration) with the extra advance, back off a bit on how much you've advanced it.
This helped my MPG on my '66 Dodge Polara (383), '69 Dodge M300 (318), and '77 Dodge B200 (318). Advancing the timing gives the cylinders more time to burn the fuel charge before the exhaust valves open.
This may also help pass the HC part of emissions testing. (HC = hydrocarbons = unburned fuel in the exhaust system.)
2. Change your driving style, especially accelerating from a stop. Double or triple the distance it takes you to accelerate to speed. (Try thinking like you're driving a heavily loaded 18-wheeler and ease your way up to speed.)
-1 vs. -3 engines:
The main difference between 'standard' (-1) and 'industrial' (-3) engines is the crankshaft and, possibly, the camshaft. Most 'industrial' engines have a stronger forged steel crank instead of the more standard cast steel crank. This is why race engine builders like to cannibalize motorhome engines.
The only sure way to tell if your engine is a -1 or -3 is to drop the oilpan and look at the crank. (Cast cranks have a narrow parting line and forged cranks have a wider parting line.)
The best way to tell is to look for the engine serial number stamped into a machined pad on the engine. (On a LA small block, it's on the front left just below the left cylinder head ... I can't recall the location on the B big blocks.)
Both types of engine used the same blocks so the block casting number is meaningless for telling the difference.
For most of us, discussion about -1 vs. -3 is moot. Broken crankshafts have been extremely rare among everyone except drag racers since the mid-60's and, hopefully, you're not stressing your engine to the point where 'standard' versus 'industrial' becomes an issue.

Griff, Thanks for the info above (you posted while mine was waiting for the net so I'm not going to sweat it on the about 30 hp between the two engines).
So far I've done the fixes "mentioned" including tweaking both idle jets in by 1/2 (other than timing Griff) here and this Sunday after I get done "playing" 2nd cook for a pancake breakfast I'll be changing the oil.
Tuesday I'll see if I've gotten closer to the thing passing.

So no work on the ancient RV...though we did buy a replacement battery for the generator.
