Hi Vincent,
Here is a link to one thread on MLU about Ford V8 engine colour. There may be others.

As can be seen there is plenty of debate about correct engine colour.
I painted my engine "engine gray" simply because the original colour was gray but since then have learnt that gray paint could have been applied to a reconditioned motor. I have seen at least three other original military engines painted gray but they too could have also been rebuilt. If so, and done in service, it still could be considered a "correct colour"
I am happy with it anyway. Light colour makes it easy to see. My marine engineering shipmates told me their equipment in the engine room was always painted a light colour to make it easy to spot leaks. Good a reason as any to leave it gray!
In the absence of wartime colour photos, or sighting Ford Canada production specifications to end the debate, all that matters is what pleases you.
Cheers,
