The crossflow head engines have the combustion chamber in the piston 
instead of the head, so the pistons are very different.

>2) Is this a 3 or 5 bearing motor (or did they make both)?

The 1340 is a 3 main bearing engine, the book I have does not recommend
trying to increase th power much because of the hollow crank, long stroke and
short rods.

I have a good book on these motors, "Tuning four Cylinder Fords" by Paul
Davies.
SpeedSport Press, ISBN # 0-85113-076-3.  I don't know if it is still in
print.

The 1340cc engine was used in the Ford Classic and early Capri, so if you 
can find a manual for those it should work.

>4) Are the Dell'orto's going to be too much carb for this motor

The book mentioned above says not to try to increase the power of the older 
engines, get a later, larger motor first.  If you can find a Cortina GT 1600
cc engine it
would be a lot easier path to more power.

Hope this helps, Don
