Napa brand 20w50 on budget or Mobil 1 15w50 would be my picks
The timing is from Mopar Performance Small Block V-8 Electronic Ignition Kit and verified with a degree tape. Dizzy curve was adjusted by DynoTune.
I also installed O2 sensors and verified it is always slightly "rich" since local gas is 10% ethanol.
It takes about 10 minutes at WOT for them to noticeably glow. Someone in a Mopar forum said they were used for generators in the Pacific 24/7 and the manifolds always glowed. The water pump is 2x the size of a basic 440 and feeds the heads directly...

The pic reminds me, there is room for a giant oil filter, what is the largest that will thread on?
What a cool motor home! I don't know about Mopar motors, only Chevy Big Blocks, but I'm guessing any 15w-40, 20w-50, 15w-50, even a 5w-40 if it gets cold when you are using it would work fine. Old school rocks!
Thnx, The scheme is '63 - the only year the side trim was added.Sir, nice old vehicle. I’m liking the paint combo also 🍻👍
That came before SuperFlo … nice collector item …!Lots of good input - Mystic, Delvac, HPL, M1; so now there is the paradox of choice (although I'm leaning HPL)
And to further add to the pot there are numerous "M1" synthetics for one to choose from
Turbo Diesel Truck Full Synthetic
Extended Performance Full Synthetic
Fuel Economy Full Synthetic
High Mileage Full Synthetic
Synthetic Motor Oil
Truck & SUV Full Synthetic
although only "Synthetic Motor Oil" is available in 15w50.
This is why it is hard for an average joe to pick one, maybe as intended...
I also have this can of 10W-20W-40 Enco that came with the RV, presumably used by a PO. Label touts many advantages:

The conventional Valvoline VR1 20w-50 seems to have a rap for thickening when sitting. Another common problem with RVs like mine is that they can sit for months without use.Given your local climate; M1 15w-50 or Valvoline VR1 20w-50 would be my choice.
Odd, you mean beyond the grade? And this was measured how when cold?The conventional Valvoline VR1 20w-50 seems to have a rap for thickening when sitting. Another common problem with RVs like mine is that they can sit for months without use.
Yeah, likely apocryphal reporting from some car owners who used it...Odd, you mean beyond the grade? And this was measured how when cold?
I found that the bolts were a tad loose after I bought it and had to re-torque properly. Some narrow-tube headers might be in the future (they were a great add to my 454 Southwind) but not a priority now.Those engines and the 440 were always breaking exhaust bolts off of in the heads. I used to R&R the heads without removing the intake manifold.
The studs on the ends go into the water jackets too.
Seems like another good possibility https://www.redlineoil.com/10w40-motor-oilJust to throw out another suggestion, Redline High Performance 10w40 is heavier at operating temp than conventional 20w50. I have a neighbor who likes it in his GM 366 tall deck. Pao/Ester based stout add pack.
