The car has a BS3 management system.

I apologize in advance for my lack of knowledge. Any help would be appreciated.

Just a couple pics of the painted engine bay.
WOW big issue discussed a lot on LT1/LS1 and impalassforum.com.

The 24# injector seems to work well with 350's with just about any cam.
Fuel Pressure can be cranked to 55psi to meet demand.
I use a PCM and tune with LT1 Edit or TunerCat.

Some move up to 26# Injectors but most stick with the 24#er's.

30lb Injectors are used when our www.ECIRS.org racers move up to 383/396/409 LT1 engines and or power adders.

If you have a PCM and Laptop,
FreeScan is available to help tune the engine by recording a run.

I use a Walbro High Capacity Fuel Pump, far more than the car needs.
Infact may go back to the stock pump.
