Did my Focus last year 1600cc to 5000cc, no problems, except they left the old engine number on the v5, I assumed wrongly that they would delete the number as I didn't supply the new number so if you know the new number fill that in as well.

Does your 302 have any stamped engine numbers?
Mine just has some cast in ones and nothing that identifies it as an individual engine

If I gave the DVLA the cast in numbers there would be hundreds of cars with the same engine number ??
