Yes Mike
I looked at a Chev site which I can not relocate and it showed clearly the Canadian R (right drive) engines changed to longer numbers in 1941
I have absolutely no doubt the engine in my ute is 1940 verified by both casting number and engine number from various reference sites. In all probability it is the original engine for this vehicle but who knows?
Have a look at this

This is from Woodville, were there any other body construction sites or did they all use Woodville bodies? Interesting the large number of war-irrelevant makes that they kept punching out through 1941.
Interesting thing is 2,510 what I presume is the civilian style Coupe Ute built to 1943 but only 98 AMF Coupe Ute. I have not got the figures for 44 and 45 but even if civilian type production ceased it would appear there were vastly more civilian style than military.
