I heard that 24# Ford Injectors use different flow charts (or something) Then say Accel 24# ones. So do Ford and GM injectors flow the same, # for #.

 

They flow the same, just ford injectors are rated at a lower PSI. That means that putting a ford injector in your gm car rated at the same 24#s will give you more fuel unless the fuel pressure is lowered.

 

THERE ARE FORMULAS ON THE MSD WEB PAGE. A FORD 24# IS RATED AT 37PSI AND UPPING TO THE GM PRESSURE OF 42+ GETS YOU 28#. THERE ARE ALSO FORMULAS TO CALCULATE THE SIZE OF INJECTOR YOU NEED FOR YOUR ENGINE (I AM SURE YOU MUST KNOW THE HORSE POWER). I AM USING THE FORD 24# ON MY 406 AT THE STOCK GM PRESSURE AND EVERYTING IS WELL. I DO RUN A LITTLE RICH, BUT I HAVE NOT CHANGED THE COMPUTER CHIP YET.
