Hey everyone I was hoping to get some info on what carb I should run. Im gonna drop in a 86 or newer 350 that my dad has laying around with serp. system, gonna drop my vortec heads and edelbrock air gap intake that were gonna be used on my 355 but instead gonna put these on this 350 instead to get the car going. I have a holley 750cfm carb custom rebuilt by "rocket" from here, not sure if lurks on here still, but im afraid and think that 750 carb will be too big for the regular 350 and dont wanna run rich. So I want to buy another carb for the time being, what should I go with? Thinking maybe like a 600-670cfm holley? Let me know what y'all think. Thanks for the help

If it's pretty stock, 650 is more than enough.
