I have a TBI 350 (5.7) that has 55 pph injectors in it stock, I was at pic n pull a few weeks ago and found a TBI caddy with a 6.0L engine, so I pulled the injectors, they look like they are larger than my injectors, my stock injectors have a small pin in the center and the fuel sprays out around it, the 6.0 injectors don`t have the little pin in the center were the fuel sprays out of, so the opening is larger because the pin is not there, the number on the injector is GM61906, using this number, can someone tell me what pph rating of these injectors are ?, and can I swap them for my stock injectors ?, will they work ?, thanks for any help you guys can give me.

the GM61906 is probably the date code....

if the p/n is 17081030, 031 or 033 it is the same or nearly same flow rate to the injectors you already have.
