I think they are a GM fuel injector, I had a set before the FIC ones I have now and they were like 42 lb injectors? http://www.injectorwarehouse.com/injectors/gmc/mp3058.htm

Look for numbers printed on top of the black plastic part of the injector. Those will tell you what size the injectors are.

found info out the are a Delphi/Rochester 65lb per hour or 680cc injector this build will be a 2.4l with forged internals and 1g cylinder head are these injectors worth installing or look for something different. if so is there somewhere I can send them to get flow tested and cleaned. thank you!
