What are your needs or HP goals? If you know your HP goal, then use this formula:
(HP x BSFC) / (# of Injectors x .8)
This will yield a per injector flow rate in LBs/HR
HP = your desired HP you need to support
BSFC = Brake Specific Fuel Consumption
.8 = represents 80% duty cycle
(HP x BSFC) / (# of Injectors x .8)

Your car has 28.8 injectors now if they are stock. Ford "Red Tops" are rated at 30lb but run about 37-38 (I believe) at C5 fuel pressure.
The question is "Why do you need bigger injectors?". The 28.8's will support up to around 425 RWHP.
