I appreciate the info, kinda looks like I gotta little bit more than what I was planning on using for my build

more isnt an issue. less is. i would send them out and have them cleaned and flow tested before using them. 40 bucks to know they arent junk is good piece of mind

I agree with you on that, I dont think 40 or so more bucks will hurt to spend, I only have 50 bucks invested in them already. Do you recommend a decent place to get them cleaned and tested

the vendor here fuel injetor clinic would prob be a good guess to start.

I have the same injectors and love them, scaled them to 863(on pump) and they run like a charm. I've seen alot of searches for these lately. You should mark the thread as resolved, it helps.

when you have them cleaned and tested dont forget to have them replace the orings and seats

yeah bigger injectors and can have duty cycle lowered and its just like having a smaller injector.

I appreciate all ya'lls help with the info

Those are the stock injectors from a LS1 right? I ask cause I have a part number of 17104988 which one website rates them at 72lbs/hr-765.7cc/min, and the other at 75lbs/hr-787.5cc/min. I also have a part number 17104959 which is 95lbs/hr-997.5cc/min. I'm not sure what these come on. Though the website says its the OE part number, but it lists no vehicle/engine, unless I read it wrong. Anyone have anymore info on these GM injectors?
