I'm sorry, but I just HAD to step into this thread....
As far as the origonal post goes, the Ecoboost V-6 is a very WIDE motor, especially with the OEM mounting of the turbos (Which would be about half way through the frame rails of the ranger). The 4.6 is wider than the 5.0 and has been done in the ranger but is very VERY tight.
But now to this Tonka fella....
Show me a supercharger on a 2.3 4 cylinder that can run with my V-8 ranger last season when it was Naturally Aspirated? Please? There are a few nasty 2.3 turbo's running around, but they are big boost trucks, and started with the SVO motor which is NOT a dime a dozen.
a 2.3 motor with a blower, or a turbo will inhale JUST as much fuel as a V-8 powered truck if you are beating on it, and a V-8 will be FAR more 'relaxed' on the highway and can get comparable MPG. More to the point, my truck (V-8, and SUPERCHARGED, which I'll get into in a second here) Gets 19mpg on the highway doing 75 with a 4.10 gear!!!!! I'll probably nab mid 20's with my 3.55's that are going in this month.
And as you already said, a worked 2.3 would need to be SCREAMING to make similar power as a VERY relaxed/cheap/easy to build/huge aftermarket V-8...
85 Ranger hit on the point about there is little/no weight difference, and the 5.0's are just as common (If not MORE common) than the 2.3's, and it will cost far more to get a 2.3 to comparable power levels of a stock 5.0 than it would cost to just drop in a 5.0. And yes, 85_ranger... the 5.0 can be supercharged too, far easier IMO
A Supercharged V-8 does quite a bit to a ranger. Mine runs a 13.90 with a 1.99 60' on a 235 width garbage street tire. BONE stock 5.0, and only 5PSI on the blower. Haven't twisted my frame, Using ford OEM 4.0 OHC motor mounts, ford OEM slip-yolk from a 98 Crown Vic, OEM 4 cylinder driveshaft even....
My truck has a stepside (Fiberglass) bed, and yes, it takes finess to get traction, but if you had a blower on a 4 cylinder putting out similar torque/HP you'd have the same issues. For perspective, My buddies 2005 Comp G Grand Prix (Supercharged V-6, FWD) Can cut a 2.06 60' on stock tires, so my truck launches just as hard as a high torque FWD car, and additional perspective would be the 2006 SRT8 Challenger at the track the last time I was out cutting 2.1-2.3 60's all day long.... The driver plays the biggest role in launching a vehicle no matter the weight or configuration.
There are 2 trucks on these boards that come straight to mind that run 11's without any frame modifications, both are naturally aspirated.
Truck was shutting down 1000 RPM early due to my tune, only dynoed 235hp, but put out 300tq at only 3400RPM. The shop running the dyno said the truck should have comfortably put down 250-255WHP if it wasn't shutting down early.

You can get a supercharger for a 2.3L 4 banger that'll make it run with the stock 5.0's so why the hell would you go with a 5.0 that's gonna guzzle gas even when you're not on the hammer? Why put the extra weight of a V8 up front (in a vehicle that's already too front-heavy) when a screaming 4 cylinder will produce the same amount of power and they're a dime-a-dozen at the junk yard?

Somebody pointed out to me once, the old 2.3 weighs about the same as the old pushrod 5.0.
They are both fun engines, but the 5.0 has more torque... and can be supercharged too.

What would a supercharged 5.0 do to a Ranger? I mean besides twist up the frame and smoke the tires?
