I believe a 460 will fit right in where a 390 has been. That would be my choice
Takes more changes to go 460 than change 360/390.
I worked a '75 F 350 a few winters (Holmes wrecker bed) My last tool truck was old F 500. Both trucks had 460 in at times, but I went back to 360 in both. The bigger engines did make the truck go faster stoplight to stoplight, but the way I used them the extra fuel cost hurt. The trucks where never MT, the one ton was loaded or overloaded.
All the time I worked those trucks I was half-donkey shopping for a 330 inch Y block from early '60 like I had in the '56 F 5 with dump bed. No issue moving 5 tons of rock, or Bobcat on the trailer, did pretty good on gas.
BTW, once got a used 460 mounted in a friends truck. When ready to put clutch in we discovered the crank did not have hole for pilot bearing.
