Two atmospheres are better than one
Sounds like you two need to name the terms of the agreement and (electronically) shake hands.
Brainstormin' 440 vs 5.9 ...

I'm talking long term as the project progresses, equal progression the 440 is hard to beat.
The only thing this test proves is the backward progression of the 440.
If it were a 68 magnum 440 and a 73 360 we'd be having a different conversation.
But here we are.

But it’s not and it never was. If it was a blown 426 hemi and a slant 6 we’d be having a different conversation also, but it’s not.

We all know with money and time that a 440 can be built to make more power than a junkyard 5.9 with a cam. Thats not news.
That's a hot rod cam for a 318... they are in the .3XX lift range. Actually, I think the cam he listed may be a spec hotter than the RV cam, but I may be wrong...
I am not afraid of where we are. I'm cheering for the truck, which means I'll give the 440 everything I got to give it it's best shot.
What year 440 is that again? I’ll pull my R / RM chassis manual and bring up some specs here.

The net 195 hp version. lol
My manual is a 1972 with 440-3 specs, so not a true apples to apples comparison. Camshaft specs appear milder than the Melling SPD11 stock replacement camshaft.

But, before we go any farther, let’s go back and look at the prior example given to us early on in the thread. Stock low compression 440, stock cam, 750 Edelbrock carburetor, 1-3/4 tube headers, and an M1 single plane.
Get a proper timing curve in there with all the advance in at around 3500. Even with the extra weight of the big block, it’ll almost certainly have to break into the 13s.

Am I wrong to say I don’t think a 77 rv 440 had that much power and torque? I know it’ll have an intake, carb, and headers, but even with that I’m pessimistic. 318WR is a great tuner and I do hope my 15.3 guess will be too high (no I’m not back pedaling lol), but 311HP/422Tq just seems high. I’m also no expert so I’m not arguing. Just questioning.
I believe the earlier year 440's, though not the HP version, still didn't have their pistons down the hole as far as the later models. I could be wrong. I certainly am not the expert here.
that's gross hp, not hard to believe with headers and single plane intake
How far down hole did the pistons measure in the ‘77? Given the compression numbers, it probably would make the most power by way of thermal efficiency on pump 87.
didn't measure them. BUT... had some good mopar people on my channel said their's measure 200 thousands down the hole. Actually, two different guys said 200 thousands
I would expect over 300 gross with headers.

Then we come to the issue of it being out of breath with the 4.30? Gear. Now bring in the double edged sword of the 3.23 not being enough gear. How tall of a tire is this thing on again? Stock convertor? If it goes ANYWHERE in the 13s I’ll PayPal 20 bucks to whoever got closest on the guess.
I do have 3.91's in the duster I could borrow. 29" tire. Hughes off the shelf converter.
And, I'll pay for the gas, the entry fee, the food, etc.....
What was the trap rpm with the 5.9?

Borrow what you must. My offer to the winner still stands if it’s in the 13 second range.
I've already said my number was just thrown out for a number. Get over yourself already.
Generous of you. And I'm going to try hard to make you spend your 20 .. LOL. Gears are the only thing I plan to change if it runs out of lungs at 800 ft or something. Should be fun!!
