I have a set of injectors off of a 89 or 90 Thunderbird S/C (yes I have 8 even though it was a 6 cylender) They are red tops with the following #s E9SE-B1B on one side and 0280150756 on the other, two of them are odd ***** with red tops but the following #s FOSE-85A and 0280150941 on the other side.
The guy I bought them from removed them and went to a FP performance high impedance set-up with big injectors, hence he now has no use for these, he said they were 32#ers but wasnt sure as his car ran lean until he bumped the pressure on it up to 50 PSI ( 86 T/A) So does anybody know what these creatures are?

I would have them flowed before using them, especially since they have different part numbers.

I plan on having them cleaned and blueprinted, *Update* I found out what they are, ford calls them a 30 # injector, the second part # I have is the service replacement for them. They originally came on the 90 to 93 Thunderbird S/C (3.8 supercharged). Thanks Rick for your response.

Thanks madwolf, that info you have there is more indepth than what I have found earlier. So actually they both are slightly different. I may have to go buy 2 to replace the oddballs. Thanks. Oh in my first post I meant he got a low impedance system, my bad.

Perry, not sure about the oddballs, but I wouldn't use them.

Here's the only thing I could find:
