Re: 350 injectors
I've searched and searched and it seems people like buying injectors not knowing the flow rate, anyone know about these injectors? I'm guessing they are 55lbs but i'm wanna be 100% before I buy.

Note TJ7 are not GM. Aftermarket? But you are correct. Price is right.

Re: 350 injectors
No need to change from 55 to 61 injectors, flow capacety is too similar, just ad some fuel pressure with your stock 55 injectors.
If 55 will not deliver anough fuel with adjusted fuel pressure, you will probably need bigger then the #61/hr.

Re: 350 injectors
-65 injectors @ 12psi flow 124.9 #/hr, good for aprox. 236hp
-61 injectors @ 13.5psi flow 124.4 #/hr, good for aprox. 235hp
-55 injectors @ 17psi flow 125.8 #/hr, good for aprox. 238hp
Hope you understand it now.

Re: 350 injectors
That thread I alluded to above somewhat explains GM injectors can be run at higher fuel pressure. Just need to be assurred your fuel pump and regulator(spring) can support higher pressure. You may need a TPI pump and replacement spring if higher than 13 lbs at WOT is needed to fuel motor.
