fuel system for juiced 418ci?
what fuel system to use with this setup:
Forged 418ci L92 Block, Mildy Ported L92 Heads, Custom 243/247 .639 .622 111 LSA Camshaft, 11.1:1 Compression Ratio, L76 Intake Manifold, LS2 Throttle Body, TNT 250 Shot Wet Kit, No maf, Hptuners 1 bar speed density tuned.
Most people advised me to keep the stock l76 injectors (40lbs), rails and upgrade the fuel pump only but i think the motor will do over 700whp and 40lbs will be maxed out.
Any clues?

The Nitrous will not tax the injectors but I still think 40lbs is a little small for the motor.
LS2 fuel rails $199.99
Mototron 60# inj. $430.00
Now the fuel pump gets tricky as you may get away with one pump and a BAP but I really think you will be on the edge of hurting the motor running lean. We have a new dual intank Walbro fuel setup for the GTO but it will require new lines and front mount regulator. Just like our Stage3 Street kits for the F-Body We now offer a Stage 3 Street kit for the GTO.

I would go with what nate says. I have maxed out my 42 svo injectors, bap and intank 255l with my 408. The stock fuel filter is going to hurt you also. you definitely need to go with larger feed line, FPR, and the 60lsb injectors are not a bad idea. After 80% duty cycle things get rough for injectors.

so will this work on a l76 intake manifold? i mean the rails and lines? and is the stock ecu for 60lbs injectors? will there be any modifications needed for the fuel system and pump
