Exactly! Centre shift is floor located, As opposed to Column shift (as on sedans)

The "U" code applies to all of BMC cars, not just Healeys. Some of those cars have a gearshift on the steering column, some on the floor. "Center shift" as applied to the "U" means a floor shift, not the position of the gear lever on the floor.

I’m perplexed by the references to the “U” in the engine number in the documents which Scott attached. The first attachment states that 3000 Mk I commenced with engine number 29D-U-H101 and ended with 29D-U-H26212. The second document states that “U” indicated a center shift gear box. We know that all Mark I Healeys were side shift; the center shift was not introduced until near the end of the Mark II BN7/BT7 run in November, 1961 at engine number 29E/2246, chassis number BT7/15881 and BN7/16039, per Clausager’s book. Hence, the 2 documents conflict and my confusion over the statement that the “U” refers to a center shift box.
Clausager states: “However, the engine prefix was later changed, possibly coinciding with the introduction of the six-port engine in 1957. These engines had the prefix 26D, followed by U on non-overdrive cars, and R (or RU) on overdrive cars, finishing with the letter H for High compression” (Original Austin Healey, Clausager, 1990, pg. 87).
Case in point, my BN7, produced 26-28 September, 1960 is chassis number 12656 and engine number 29D-U-H/22855 (my car was originally a non-OD car), verified by the BMIHT certificate. The gearbox is a correct side shift unit. This is in agreement with Clausager’s description.
So, the assertion that U denotes center shift is quite confusing. Anyone else able to weigh in?

Hello Mitch and Seasons Greetings.
The attached files may help a little but the casting numbers are not related to sequential engine production.

Hello
How do you ID an engine block/or head……that does not have an ID tag?
Do the engine block casting numbers mean anything?
