I had a Spearco Dual stage water injection system I put on my 71 Bus with
the dual Kadron carbs.  They recommended using distilled water and that got
a little expensive, but when I switched to tap water, the orifices clogged
frequently and it became a hassle to do.  It did work though, but the old
1600 was under so much of a load, the gallon resivoir drained pretty
quick.  The dual stage part was dependant on vaccum load and we all know
where that left an old 71 bus!!  Don't remember what I paid for it, but I
got it at the local JoeBob speed shop.
