I was wondering if anyone could help me.
Is it possible to ascertain an engine's capacity by using engine numbers rather than having to (I assume) remove the cylinder head?
The engine is in a 1939 Commer Q2, it's a straight 6 engine.
Is there a registry I could use or something like that?
Cast into the side of the engine are these numbers:-
85 X 120
C 20xxx (I've not given full number here)
Many thanks!
