1999 FRC preparing for LTA Land Speed Event. 4.8 engine .030 over Texas Speed Heads and cam. Holley Dominator stand alone EFI. Want to use the Holley DBW harness- what do I need. Would consider DBC as getting close to event need to get this done.

Appears I need a different throttle body and gas pedal to match the harness;

Throttle body  GM P/N - 12570790 or GM P/N - 12580760 is one better than the other?
Gas Pedal GM P/N - 10379038

Wow no responces??? It appears your question is above the knowledge of this site. If it’s not a fast intake with a big throttle body bolted on it, they probably don’t even know what a Holley carburetor is. I know what a Holley is but I can’t help you, I haven’t mixed any old school with the newer technology . Good luck with your project.

That's a pretty condescending way to say that nobody who read this has experience with this specific, fairly rare setup. Nothing about the questions nor lack of response is worth the rudeness.

To OP: Good luck! If you do figure it out, please update us, so the knowledge is preserved.

For what it's worth, I know enough to tell you that he's talking about standalone EFI system, not a carburetor.

55chevr, I think you'll have more luck in the Forced Induction section of this forum, since that's where the majority of the guys running standalone setups are. LS1Tech would be another resource. Good luck!

with the forced induction section and hope it does not get bounced back to here. LS1tech is another good option. C5 tech is not the place that would get responses for an aftermarket ECU as naturally aspirated street builds rarely need an aftermarket ECU in a C5.

I would say the autocross section but the aftermarket ECU guys usually jump directly to electromotive. G Speed has done Electromotive conversions but that is big money.

Think youd have better luck contacting Holley in this case.
