hey i have a quick question, a friend wants to sell these injectors from his 5.3 turbo truck, he says they are delphi 42, all i can find on them is Delphi brand, 3061A C3B and a number scratched, i took 2 out of the rails, one says 56 and the other looks like 90 (see the pictures)

anyways i want them from a 6.0 224/224 cam and a bit of nitrous and later turbo, is this what i need? thank you

They look like the 8.1 Multi-tec II Delphi injectors. The are a direct fit into 5.3 and 6.0 engines (1999-2006) the flow 43.82 lb/hr at 4 bar (GM fuel pressure) and are good for 400-500 rwhp--depends on power adders and tune.

Advantages are direct replacement for current injectors, disadvantage is no published minimum injector pulse width, small pulse adjustor, etc. so you are dependent on the quality of the tuner you use.
