Water injectooy

I used A primitive holley water injectir on a modufied 455 bsck in 1986/87. It worked , but it was poorly controlled .  Has anyone used one if the AeM lr Snow performance kitz?

i worked out an idea on how how to. Plumb it with tripower.    

I will add1” spacers to all 3 carbs, and drill and tap each  venturi in front and resr carbs ( total 4 nozzles). It should work.. but the injection companirs have nothing to say on using it with Rochester 2GC carbs.  So im on my own.
