Default Got my 44lb injectors but the numbers on them are different, can someone explain?

I just bought a set of 8 44 lb Delphi injectors from a member on the board here and have a question. These came off his truck that had a radix supercharger. When looking at the injectors I noticed that all 8 are the same physically, and all 8 have the same part # of 17113739. Above that they all say 5205A but here's the kicker. In the upper right hand corner of that information, 4 of the injectors have a C3B designation and the other 4 have a C3A designation. I would post pics but my cell camera doesn't zoom or focus in on the numbers clearly. Funny thing is, I have 4 of each injector so are some of them supposed to go on the odd bank and some of them on the even bank? Any help is appreciated. I wonder how many guys are running around out there who haven't even checked.........

Could be a lot #? All 8 injectors are the same and interchangeable, no difference between banks.

It just seems weird that 4 of them are C3B's when the other 4 are C3A's. Now, if I recall correctly, when you buy a radix the injectors come placed into the intake manifold right? Does anyone with a radix care to take a look at theirs and see if they have 2 different types of injectors on their intakes? If so, what bank or cyl's are the above injectors located in? I will take pics of the numbers to look at. I will be home in an hour and a half to post real pics.

The upper right # is what he is talking about.
You can e-mail delphi @ contact.delphi@delphi.com
They were very prompt to give me the flow rates for the one in the pic.

Thank you so much and I will email them now. For the life of me I could not get my digital camera to focus in on that small font. I will email Delphi and post up what they say. Thanks for the email address
