I looked this up in my book "Rebuilding and tuning Fords Kent Xflow engine", but not much joy.  "711M" means that it is
a post-1970 engine, using larger bore cam followers and a stronger block and is to be preferred over the earlier engine.
The rest I don't know, but I'm told that there is also an AX block, made in South Africa, that has been further
strengthened and is the best one to use - although the 711 is fine for most purposes below 170bhp.  The weakest point is
the valve train (A combination of using high-leverage rockers and less than perfect lubrication especially at low revs)
and non-forged pistons.  Hope this helps
