Carb advice wanted

[Pinchecharlie]

Good morning, scumitt has edlbrock avs2 carbs on sale right now for 300 bucks. Now I do t won't to start a carb brand argument so let's just talk cfm. The carb on sale is a 650 cfm. Now I think a 500 is enough for a stock 350 probably and I know a 600 is standard but would a 650 be way to much for a stock 350 ? It's only 40 bucks more for a 1406 but the avs2 looks pretty nice and it's about a 100 more for it in 600cfm. You get a free air cleaner and fender protector too. The only.thing not stock is the manifold(edlbrock perfomer) and the ignition and it's got ram horns. No cam no heads no valve work stroke or compression changes. Thanks charlie
