Al. This has been argued about before, so I will post it again. See the opening pages from a British manual below.
I'd guess the British built MkII unversals and Mortar carriers at least with 239 cu.in. engines.

On the fan and waterpumps. I would suggest in the carrier situation, the h.p. required to drive the fan is probably higher than in any other Ford application of the time. The fan blade was special and it has to work hard to force air through a highly restricted flow path. Our carriers weigh in at about 4 ton and along with the design causing air flow dificulties, they also operate often at a low ground speed. As a result there would be virtually no air flow, that is not fan driven.
I personally wouldnt be trying to run without the twin belts.
The ford v8 by design is elsewhere described as a "hot" motor, because the exhaust gases have to flow through the block. couple that to an increased capacity motor (8ba,239 cu.in.) an exhaust system designed for a 65 h.p. v8 (a morris minor sized pipe)
As you go up in cu.in., the requirement for cooling increases.
Suggestion: Dont take shortcuts with your cooling system.
