Exactly. Nobody expects the MOT tester to know. There is enough reference data available to show it's an older engibe.

The last Mini to have a pre A+ 1275 engine was the Innocenti Mini Cooper 1300 Export in 1975. From then onwards only 850 & 998 Minis were available. The 1275 re-appeared in 1990 with the A+ engine, so if it's a 1275 pre A+ then it's a pre 1975 engine. The differences between an A & an A+ are well documented and the engine number will determine exactly the manufacture date of the engine. All the data exists.

So a non mini enthusiast tester knows the diffrence between a A+ and A series engine, also every tester knows what a 1971 engine looks like.

He doesn't need to. The engine number identifies the age of the engine very effectively. There is adequate information available as well.

ah so the engine number does hold information on the age of the engine? So in effect the tester should just be able to look up the engine number to identify the year?

I think you might need to get that information from British Motor Heritage as it may not come up on the DVLA data available to MoT test stations. Of course, a Mini-knowledgeable test station will know what a pre-A+ 1275 looks like and therefore know it's a pre-'75 engine.

Realistically, what you're proposing to do (if done properly) shouldn't pass an MOT. If you were putting the original specification of 1982 Metro engine in, and IF it's still got the original engine number, with the paperwork to prove the engine's age then it would pass.

If you take the engine to be rebuilt and it gets a new number, then there's no proof that the engine is a 1982 engine. IF you kept the original engine number, it would be fine though.

why would you change the number of an engine after re building it?

Surely the last A series 1275 in a Mini was in the GT which was produced upto 1980, where I believe only some of the last actually got an A+

and don't forget non-mini sources such as the allegro, princess and if you fancy a 12V engine, the marina and ital
