Yeah, in light weight rig's like ours it works well. I don't know about an F100 though, seem like the big six is a no-brainer there. Although they did drop the 250 in those big ol lead sled land yachts of the early 70's lol
The US 250 had gross hp ratings of 5 hp more than the 240 engine used in Galaxies, Torinos and F100s till 1973.
155 to 145 hp gross. It was 99 to 102 hp SAE net from 1968 to 1980. The 250 was actually a truck engine option for the Ranchero, which migrated to the Torino name rag from the Fairlane in 69.
Even the 115 to 119 hp 255 4.2 liter Debored 5.0 engine had a stickshift SROD and 2 bbl carb base engine in the F150 in California from 80 to 82 with MCU computer. It was a really good enginee with 195 to 200 ft-lb and a 170 style 244 degree tractor cam bringing the peak torque in at 1800 to 2200 rpm.
The 250 the last year offered (1980) made 99 hp and 185 ft-lbs.
See post #5 29 October 2017 with pictures of the early iron head in a 79 Australian 250 Cross flow F100 truck. Some F250s got this engine with the Dyna axles and carried 4.56s or somesuch with the T18 gearbox with an Australian Top Loader bellhousing from the Cortina 250 six cylinder.

While the F100 became the F150, your 351M and 400 V8s were decarbed snd took a deap power cut for the Fed Emissions (138 and 163 for 1981 while our 4 bbl 351C made 216 hp from 76 to 85)
From 1977 to 1985 in Australia, the 250 Cross flow with 121 to 147 hp at 3800 and up to 237 ft-lb at 2200 rpm while the 73 US emission spec sedans did 121 to 131 hp and about 230 ft -lbs. Less emissions gear and 9.2 to 9.4 compression with 1 or 2 barrel carb.
