Just my opinion.
Only you can decide what is best for you and your truck, but since you asked.
As far as "bang for the buck" and streetability, <-- is that even a word?
and keeping it all ford, 302/AOD.
Dr. Smith's 289 sounds good, but the C4 is not O/D, so you are still looking at some RPMs at highway speed. Maybe you could sell the C4 and buy an O/D?
But then, I'm a Flathead guy, so what do I know about all these newfangled engines with rocker arms and all that?

I know it's heresy here, but if you want simple, there's nothing easier to install than the SBC. I've been favoring the mod motor lately until I just found out how BIG the dang things are. They are bigger than a Chrysler Hemi! (tho a lot lighter) If I were going to a manual tranny, I'd spend the extra $$ for a T56 6speed, especially one with the double OD 5th and 6th. You could then use a lower ratio rear and still drive it around town. They are bulletproof, having been originally designed for the Viper V-10! I love mine!!!

I think for an F-4, the AOD is not adequate, nor is a C-4. Something in the C-6/TH400/4L80 class would work. For a manual, I don't know that I'd trust a T5 or a T56 in a heavy-truck application. If you are keeping the PTO setup for the dump bed, I guess you need a truck tranny with those provisions. ZF, heavy SM-series, or a heavy New Venture.

My thought's-
6BT/4BT cummins
NV4500 or a Spicer
Ford used both the Cummins and Spicer, I don't think they used the NV4500.

I really would like to go with automatic OD although if I could find a Dana 70 with 3.54, perhaps even 4.10 gears it would probably be driveable without OD. The challenges on a truck this size are a bit different than to modify a smaller truck. Fewer final drive ratios available and the wheel off set is not nearly as available as for the lighter trucks. Then there is the challenge of getting the front hubs configured to match the later eight lug dually wheels and eliminate the WMs.
And Ross, thanks for putting me onto the Cadillac idea, BobbyT has given me much information there.
And AXracer, you're too much of an enabler.
I figure the SBC would probably be the easiest and most available. Thanks to all for your input.

Help me decide what engine I should install in the '49 F4. I was originally thinking 351 ahead of a C6 but realize I want an OD transmission to get any road speed. The old Timken will come out and a sixties vintage DRW rear end will replace it. Road friendly ratios are limited in these early rear ends. The later Dana 70s are too wide to fit under the Ford script stake bed and still would not give acceptable road speeds without OD.
I really don't want to get into a steering box relocation or swap, that may be involved with a V8 install, as my box is tight. I don't want PS.
I don't know that I really want to go with the wiring involved with fuel injection or that of the electronic transmission controls.
So what is a relative simple replacement for the flat six? I am easy on equipment. Would the Ford AOD hold up? Would I be better served with a SBC and a Chevy OD transmission.
Discuss.
4.9, 300 CID six
Mod motor
351, 302, any SBF
460,
SBC

Hey Ray,
Ahhh.. I was enjoying watching your truck haul all that wood &
I was jealous of your ability to just dump it out. What caused you to change your mind & go with a flatbed & toss your engine? Did it blow a gasket? Just trying to understand your thought process as it looked to be running & doing work.
