So far we have not found any other markings on the block other than a cartouche on the bell housing where we expected to find the engine number. I interpret this to mean that it is indeed a 3.6 litre engine.
Can anybody help please?

Hi Alastair,

I believe those are just some form of foundry marks and have no bearing on engine ID. I have looked into this before and never found an explanation of what they meant. I have two 1946 C69A, 239 CID engines with different marks as shown.
I doubt being of North American origin they would be specifying engine size in litres back then also.

Cheers,
