My cars had an engine change at some point. The engine number that's on the V5 is C318-03-15AJ.
Found this on the internet "The US-built 1967 LA 318 has engine number prefix C318, while the Canadian 1967 poly A 318 has engine prefix CC318. (The first “C” stands for the 1967 model year; the second “C” in the poly engine stands for Canada.)"
So it looks like I've got the later engine. Any idea what the rest of the numbers/letters mean?
Thanks
Andrew
