I posted this information previously but I'm not sure it ever showed up.
Sometimes my copy of my posts to the list don't appear in my inbox for
several days.
The "U" in the engine serial number refers to a gearshift that is on the
floor (in the center of the car), rather than on the steering column. BMC
built several other types of cars with the column shift. The "U" simply
provided a code for the non-column shift. It did not mean "center shift
rather than side shift".

Subject: Re: [Healeys] Engine number
Hello,
The engine serial number below is definitely from either a BT7 or BN7 built
between July 59 and Nov 59. It would have two SU HD6 Carbs. The Mk2 had the
engine prefix "29E" and had three SU HS4 carbs and started production in Mar
61. The side shift transmission continued until Nov 61 engine 29E/2246.
I have the same BMC parts manual with RU = Overdrive centre shift. That is
not correct. All of the "29D" and some of the "29E" series engines had a
side shift transmission.

Simon,
The tri-carb engines had the "29E" prefix. The center shift gearbox was
introduced during tri-carb production. So I would go with Clausager's
explanation. Shame he doesn't state what he thought the 'U' meant.
