Chevy 388 Weiand 177 Opinions and Suggestions

Hi i recently post about my BB 555ci and receive a lot of help on tuning it right and about the parts it have.
But i also own another jeep for offroading with this engine configuration (i build it myself) :

Chevy 388, 1 piece rear main seal, internally balanced, all forged, JE pistons dish -28cc (-27.3cc real), 6" Rods, Edelbrock 60719 Heads, Full roller with Crane 119661 Camshaft, 1.5 rollers rockers ratio, Near 8.0:1 - 8.3:1 compression ratio,
Weiand 177 with 2.85" pulley and 6" pulley at crank @6-7psi, Holley Avenger EFI TBI 900cfm (up to 600hp) injection system with programable spark advance, I'm Running it at 30° of advance, i have edelbrock shorty exhaust headers 1 5/8" attatched to free 3" dual independet exhaust system. I Also have Water/Methanol system but i'm not try with it yet.

How many HP/TQ i should spec from this engine?, There's a better camshaft for my application? (i don´t spin it pass 6000rpm), i just buy a 2.5" pulley for weiand 177 to get more boost, will work or im at the limit from this engine?.

I Run Premium Pump Gas.

Thanks in advance
