The basic definition seems to be:
=========================
A Hiboy is a Ford truck that came from the factory as having the following:
- Built from 1967 thru 1977.5.
- F-250.
- 4x4.
- Divorced transfer case.
Trucks that are NOT considered a Hiboy are:
- Any truck built after mid-1977. It goes by Consecutive Build Number in the VIN# anything built starting Y80001 is a 77 1/2. **
- Anything other than an F-250.
There will always be a couple very oddball exceptions but, for the most part, this is it.
Front axle choices in the Hiboy were either the 8 lug Dana 44 or the old style low-slung pinion Dana 60 (commonly referred to as the Dana 50). Engine choices were either the 6 cylinder or 360 2 bbl. Steering was either manual or power ram assist.

===================================
It has been pointed out that the 300, 351M, and 400 were the engines available in the 77 model year.

No F100 or F150 is a High Boy.
The term High Boy, which is not Ford terminology, was originally coined by enthusiasts for 1973/76 and 1977 F250 4WD's (1977: last High Boy assembled before serial #Y20,001).
Some peeps refer to 1967/72 F250 4WD's as High Boy's.
1977: Y20,001 is the correct cut off serial number, it is not Y80,001.
This serial # info is direct the 1973/79 Ford truck parts catalog.
