What size/brand of injectors for 700+ FWHP? I'm looking to make around 700+ FWHP (engine HP) with the new setup and probably around 560 rwhp (huge drive train loss). What size and brand/company of injectors do you recommend? Thanks.

depends on what you plan to do to make that power. Also depends on fuel pressure vs manifold pressure. That differential vs power will be able to tell you what you need. My buddy's vette has 60#ers (@43.5 psi) on it with 80 psi of rail pressure it hits 80% duty cycle at 5500 rpm and 630 rwhp with 15 psi of boost and 11.7:1 AFR.

By the way, are you referring to these:
135-INJ-L107FM-8
Siemens/Mototron Deka 4 Flow-Matched 60# Style Fuel Injectors (Set of 8)
-Static flow @ 60lb/hr @ 43.5PSI = 630cc/hr (sold as 65lb/hr by some vendors)
-Coil Resistance: 12 Ohms / High Impedance / High-Z (No ECM driver modifications required)
-Gain: 0.11ms/mg, Offset: 0.055ms, Turn on time: 1.14ms @ 14VDC, Turn off time: 0.85ms @ 600KPa
-Dynamically flowed and grouped to within 1% tolerance using Racetronix custom injector flow bench
