Anyone happen to know what injectors these are? I believe they came off a L92 intake manifold. Are they flex fuel and how many #? I did search for the part # here but got conflicting info. GM 12613412 thanks for the help

No they all look about the same, i have pn 12587269 and they are supposedly 42lb flex fuel, the lb/hr rating as far as i understand it has a lot to do with fuel pressure, and few other factors..... Gm doesnt really advertise flow ratimg info on their injectors, so there is a lot of misinformation out there, when i was building my truck about the only thing i consistently found on the injectors you have is 2010 L92 6.0 so based on that id say theyre flex fuel, and as i said majority of what i found was 40lbhr with few sites sayin they are are 50lbhr.... Agree with conflicting info..... Be nuce if gm woukd make that info readily available

Yea no kidding right, I keep finding either 42# or 50#. I have a set of ls3/ls7 injectors with the spacers also but those are 42# injectors as well, and was thinking to just use the ones in the L92 intake manifold since I won't need spacers with those ones.

I would say so, im at 345 in my lifted truck and have no issues and my tuner told me the injectors i have were fine unless i started seriously looking into FI on it.... Which i will probably never do, unless i come into an lsa takeoff blower for the right price (basically free) or something!!! Almost tempted to pull my engine and trans and find something smaller and lighter to put it in just to see wht it wil do and see how much i am really losing with the lift and all that, or just find an engine dyno that doesnt want stupid money to see what it will do!!!
