All of the 3L part numbers I have looked up have been very close to 24# units at 43psi. Many GM injectors work too, but you have to convert the flow rate from 40 psi testing pressure compared to the Ford's 43 psi rated pressure.


Correction. It is the opposite.

Ford uses 40psi as it's rating point.

The bulk of the other manufacturers (GM/Delphi for instance) use 43.5psi for their ratings.


Therefore a Ford injector will flow more then it's rating at the "standardized" 43.5psi


Also the conversion to actual flow would be based on the fuel pressure at WOT.
That would be a set 55psi at WOT for return style SVT's.
It would, of course, not be a set psi level for returnless.
