water or not
wideopen231:
I have ran water in injected engine but it was way way back. We ran factory block with brodix heads injected and never ran water,never had heat issue except trying to build heat and car was consistent as could be. My combo in FED is solid black and billet heads so no way to run water if I wanted to. I have found that if you run a little rich its almost impossible to get heat you want and have a richening valve that allow me to add a little fuel to motor and cool it if ever needed. No problem with oil doing so either as long as you have vacuum pump and/or heat motor and let breath before putting away for the day.
Running water has been found to be worth cpl horses on some combo's .

Blown or injected? Do you have a data recorder and if so, what are the EGT saying? Otherwise, what does the plugs say?
xlr8:
No data recorder, and so far the plugs look slightly on the rich side.

That's a good place to start. Take notes on everything and adjust for weather conditions.

I'm not running any water. My deal would be leaking all over the place if I tried! ;) Dart Iron Eagle SBC with no freeze plugs and iron heads ported into the brass filled jackets. I can make it idle at any temp I want with stack injection and methanol. I prioritized lighter weight, more radical porting and never having to worry about leaks. I've never run a Pontiac but can't see any reason why it could not be run the same way.
