Default carb help!!

what kind of carb should i run i have a holley 750 and it's way to much carb motor sounds great but i think carb it too big due to lack of power it's pretty much gutless
should make around 325-350 hp

or do i look else where for the problem

its a sbc 350

i was think 600 or 650 what do i need

or how much can i jet the one i have down and still maintain good idle and top end 6000 rpm

9.3:1
1.94/1.5 heads
comp xe268 cam 477/480 lift
edelbrock tourqer intake

I run a 600 cfm holley, on pretty much the same set up, I came up with 583 cfm using the formula, I wouldn't go over 650 cfm.

Also your lack of power could possibly be from the cam not really matching the intake, good dual plane seems more a matched intake to the xe268h in my opinion.
