Ah Michael,
The idea of the water injection is to get water or water vapor into the 
combustion chamber where it cools off the combustion temperature, and I 
suppose drags out the time of combustion, and in general makes the engine 
smoother, quieter, and more powerful. It's like always being able to run 
your engine in the rain, but you don't have to get wet. In my early years 
of messing with the Fords, one way to get water into the motor was the 
way I used, which was to drip water into a foam pad that fit inside the 
air cleaner. It was very much like the evaporative coolers that we use so 
much in California. The air coming through the foam was cooled off and it 
also picked up droplets of water and carried them into the carb and down 
into the combustion chambers where they helped prevent ping so you could 
run more advanced timing, and in general made the engines substantially 
more powerful. 

The modern water injection is a computer controlled device that sprays a 
mist down into the throat of the carburetor to accomplish the same goals. 
Until a few years ago, Edelbrock was still making a water injection 
device. I had one on my Scout and it worked very well. I removed it when 
I put on my Holley Pro-jection because I thought at the time that I 
didn't need it anymore. I should have kept it.
