Thanks for the advice, much appreciated!
The Holley Sniper acts like a carb in that the fuel/air is combined in the "carb body" itself before it reaches the intake manifold for distribution to the cylinders. So whatever changes I make to the mixture will affect all cylinders.
If I understand correctly, Port injection sprays fuel into the intake port of each cylinder making it easier to adjust A/F mixure to a particular cylinder.
I'm running a Weiand intake and Hooker headers, Edlebrock heads. I'll pull all the plugs and, like you said, tune for the leanest one.
