NF or 7A block substitution

[Ben Swann]

NF is what I have on hand.  I am sure I can source an MC- 1 or 2 cheaply enough and have
rebuild parts for those too.

I have used a WR (10 valve) with 3B head.
Modifications was changing the return water channel from the head down to the water
pump. The 3B have an oval hole. The WR a round hole. Check with a gasket.
I also had to move the crank pulley half a cm outwards for the belt to clear the head
w/o rubbing.
Some of the work is here http://audi-claus.dk/ Claus
