Must have been some kind of engineers to only get 63.5 hp out of a 3485 litre engine. British, you say?

Quite so, but bear in mind for mil use they had an updraft mil spec carburettor and an intentionally restrictive velocity governor between the carburettor and manifold set to 2500rpm max.

In civvy guise with a single SU and no restriction or governing about 30% more was on tap.

All the WWII 15cwt trucks were given between 60hp - 70hp, doubtless considered quite adequate at the time, even the WOT2's V8s were held back to 60hp.
