650 holley?

i got a 355 wit some kind of performace cam and big valve iron heads and i got a 650cfm 4165 carb u think it will work fine or can i go larger wit the carb

For a stock 350, 650 would be a little big for normal street driving. Depending on the "performance cam" you referred to though and how you plan on driving it will make a difference. How high are you looking at winding the motor? In any event, if you're not planning on setting it up for racing, I don't think that you won't have enough carb. In that event, you may have too much.

if you decide to downsize your carb like he said, lemmie know and ill trade you. i have a 570 holley street avenger and i need a 650 or larger.....
