Idk why I even said cobras have 42# stock... I knew it was 39. I even stated that in the 1500 s/c thread... You guys are right
I think my brain is shot from my sociology essay I was writing =/

was gonna say 42s are not stock and 39s in 03/04s.
If you really want to break it down to that...
It depends on the delta pressure. Higher delta pressure means more flow. Ford measured 39 lb/hr at a lower delta pressure than is really active on the car... thus the lower rating.
Run those 42 lb/hr injectors (40 psi delta) at 55 psi delta and they magically become 58 lb/hr injectors (rounding).
Ford rates them at 48.78 lb/hr low slope, and 40.08 lb/hr high slope with a delta pressure of 39.15 psi.
