I've yet to find good info on why there are nominal and high flow injectors BOTH used in the same LT4 GenV motor? My 2017 Z06/7 comes with nominal flows I accidentally ordered a high flow to replace one. Didn't make any difference tune logs everything was just fine. I have the 2017 service manual also on USB and can't find any specs on the flow rates, etc. I would love to know the actual specs on flow rates and why there are two types? What they mean in real world exactly why they were made? I since replaced my high flow back to nominal but still doubt it makes much difference, if anything is best to go from nominal to high, not the reverse. But again I can't find a single spec so it's truly guessing?
I had my friend at a cadillac dealership look it up and it seems like the part numbers cross with 1268277 so I think we might be in good shape. I'm going to roll with it!

I'll be putting in my cam within the next few weeks and was going to do the pump and injectors then, so I'll let you know for sure if you're not in a hurry.
