street avenger vs edelbrock

I have currently a well tuned edelbrock 600 cfm carb on my 327. Its your standard edelbrock Electric Choke Performer Series. My friend has a holley 570 street avenger and i was wondering if that would provide more power. I know its smaller, but its more perforance oriented. Im running a crane powermax cam .458, .473 lift, 226, 234 duration 3000-6000 rpms, with 1.6 RRs.

i would go with holley over edlebrock in any size. but thats me.

go w/ the holley, i've got a 780 double pumper on my 350 in my big truck and it moves it down the pavement pretty well

go with the street avenger carb, edelbrocks are for people that cant tune a holley
