Morris Minor Owners Club

I've just checked the engine number on my 1953 s11 803cc and expectedly it doesn't match the recorded number . What i'm after is the capacity (guessing it 's probably still an 803 )and the approx year of manufacter? The number is 9m-u-h-593183. As a point of interest the distributor is numbered as 40561-l is this original to an 803 ?Any ideas appreciated. Cheers Dan

A '9m' prefix signifies a 948cc engine. If you check the engine block on the manifold side there should be '950' either cast on the block or on an attached metal plate.

948cc dates to late '61/early '62 according to the book.

Thanks very much for that ,today is just getting better and better as not only have I got the car up and running but you've just confirmed me having another 145cc !! extra power is always welcome.
