[Healeys] Closest to BN4L 052381

<     My bn4 came with a 3000 engine  >

The Browning/ Needham book on the A-H from 1970 has extensive detailed tuning
info on the various models.  The Tuning section for the 4-port 100-Six
consists of one sentence:

"The larger capacity '3000' engine will fit into the'100-Six' without much
difficulty."

Gergo, I don't know how late your 3000 motor is, but visually, the only real
difference between a late 2.6 and an early 2.9 motor is that the 100-Six head
doesn't have the little flat "shelf", for the Thermo-Carb sender, next to the
thermostat at the front.
