Hey guys I'm trying to get some opinions on what carb to use, my current set up is a 200, clay smith 264 110 cam, dui, headers , 355 rear, c4 trans, CI aluminum head ported, bottom end rebuilt and an edelbrock 500. The car runs pretty good but idles a little rough till it warms up my mechanic feels it's over carbed, I am thinking of putting a Holley 390 on but would like some input, any advice?
