thanks for the links and all i might still run water injection if it isnt too high dollar at least on the street car the race car runs 114 leaded fuel so no prolem there

already being worked on its my old race head so it has longer valves and
its ported quite a bit im just unshrouding the intake valves and going
with more combustion chamber volume
Unshrouding sound good. I should have done that to mine while I had it
apart. Even if your CR is no longer too high for pump gas, you might still
be able to take
advantage of water (water/alcohol) injection by advancing your timing more
that what you could run without it.
Here is a link about performance aplications for water injection
Here is some good stuff on octaine ratings and a bit about water injection
If ya have a carb, and are looking for MPG, this one may help.
Speakin o mileage, Im up to 40mpg with my programable FI 1500 with 10.6:1
CR and water injection. (over two tanks of gas, mostly highway driving and
taking it easy) Its also way faster than my carbed 1500 with street
performance cam which gets around 30mpg.
Some of the sites say you need a super fine mist for it to work (requiring a
expensive system you buy from them) but I got anti knock results with a
system made from old yugo parts and a rubber hose. It dosn't use much water,
maybe a pint or two per tank o gas.
I haven't tried water with a carb, so let me know if anyone gives it a
