I'm needing 2 350 injectors for my swap so I found this set on ebay but I'm wanting to know the lbs/hr on the TJ7 injectors also is this to good to be true for this price??

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.

 

 

350 5.7L ORG/BLK 61#/HR

That post was from RBob...

Here is the thread......https://www.thirdgen.org/forums/diy-...d-up-5-7l.html

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

 

I wonder who makes them, oh well for that price i'll chance it Thanks

 

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.

 

I'm not switching from 55lb to 61,lb I need 350 injectors unless I want to run 305 injectors in a 350

 

For exemple, a pair of:
-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.

 

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.
