The small UK (and therefore european) engine has a displacement of 2043 cc and the standard engine ( US and european ) 3285 cc.
1928-31 Model AF makes 28hp (at approx 2600 rpm ? ) but 1932 model BF (or ANF) 40hp (at approx 3100 rpm ? ).
The model BF is quite different with its valves which move (tilted) near cylinders. Two effects of this : little combustion chambers and more water around combustion chambers and intake/exhaust.
Why not make an HC head for these engines ?...
