[Chris Dimmock]

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

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.

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).
