You may be able to run it with an aftermarket ECU and aftermarket injectors and pump/regulator; I have not researched that. But the factory fuel system is very expensive.

You can run an LS9 with conventional fixed fuel presssure but will need larger injectors (production injectors are not large enough without 600 kPa fuel pressure that FSCM (Fuel System Control Module) commands when under higher load).
LS9 production fuel system is expensive, but very trick and works very well (3-phase DC fuel pump with variable pressure delivery based on ECM requested pressure). Fuel delivery for any high bandwidth engine will always be difficult (and expensive) to do correctly.
Can run with E67 production controller as well with fixed pressure.
