Hmmm....got me thinking.  There is a water injection kit manufactured by Holley (if I remember 
correctly) for older Chevy V8's with high compression (Those were the Days, when Men bored Big 
Holes into giant lumps of Iron and said, "It is Good for GM, and therefore...) so that they can 
run on '90's spec gas with no detonation.  The kit should include an adjustable computer, a 
vacuum line that runs to the manifold, and a nozzle that you can mount anywhere. The nozzle is 
supposed to be mounted on the air cleaner stud so that it fires into the primary venturis on a 
4-barrel Holley carb, but you might need to have something small machined in order to locate it. 
 It also has a plastic bottle with a little electric pump of about 1qt capacity that you can 
place somewhere convenient.  From what I remember, it is relatively inexpensive ($125??) and 
adjustable for manifold pressure cut-in.  Maybe you can  find it at a local hi-po American Iron 
auto parts store and adapt it to your needs. I was thinking of looking for it this summer when I 
drive the '68 327/350hp (slightly enhanced) 'Vette with 11.25:1 compression (Ping, Ping, Ping 
went the Trolley, but a very fast trolley indeed with 108+ Octane Boost). Maybe have it spray 
onto the intercooler with a little alcohol mixed in (it, not you)?
