Hi everyone
I'm setting up a GM Performance 620hp LSX454 with a Fast LSXR 102, LS7 style intake. I am unsure if factory LS3/LS7 injectors are up to the task but they would probably be my first choice if they were within their capability. I am no expert but capable of setting up ford injectors with the help of my Calibrated Success DVD Data. I have been going through various injectors listed on the spread sheet, the 39lb and the 47lb both listed as the same part number: M-9593-G302, at 58psi both injectors look good to me but my question here is, are either of these injectors compatible with my application regarding the LS7 style intake and LS7 style fuel rail.
