Since I have a Iroc-z w/ 350 and the OEM injectors is 22lbs/hr....is it better to buy the 21lbs/hr or 23lbs/hr injectors since they don't sell 22??

If you can't find 22# injectors, I would go with the 23# ones. See how the car runs?? You may get away with just adjusting the fuel pressure regulator or a new prom for the ECM.
Worse case you may run rich.

hm, thats odd, i cant find a listing for fuel injectors either at 22lb ratings. id go with the 23lb and throw an exhaust system on it, that will even it out!
