750cc primary injectors

I'm going to be cranking up my new fuel config soon & am looking for some suggestions for injector settings. I have all top feed injectors 756cc Primary & 1680cc secondary.

What is the suggested Primary percentage (I'm guessing 73%), Lag settings, and Injector overlap settings?

TIA.

Did you have to replace the fuel rail as well for the primaries?

Yes. They are both top feed, & I got them from Keith (rxrotary2_7) on this forum. I have the resistors in series, & -8AN feeds to the each rail.

Cool, just wondering since I knew the stockers were side feed and the fuel line more than likely wouldn't work.

73% would be the percentage..as far as lag settings, not really sure since it will vary with the manufacturer. What kind of injectors are they, made contact the tech department of the manufacturer and ask them what the lag is in ms.

The Primaries are Siemens, & the secondaries are Bosch/FORD Motorcraft
