Identifying NF engine

[Huw Powell]

> So the NF engine is the one I want. I think I remember that it became avaliable in 5ks in '86. How can I tell that I'm getting an NF instead of some crapy 2.1 that someone swaped in when they broke their NF, is there a code on the block, if so how do I decode it?

the only things I can think of are the knock sensor bolted to the left
side of the block and the transistor booster thing that fires the coil. 
Oh yeah, and no vacuum advance servo on the distributor.  Can anyone
think of anything else?
