bnickel said:i'd say it depends a lot on tanny choice as well. if you are running a standard go with mechanical secondary. if you are using an automatic then i'd go with a vacuum secondary. personally i like demon carbs for tunability and max power and edelbrock/carter carbs for streetability and dependability. but the cfm ranges everyone has suggested are pretty much right on, but demon seems to rate their carbs a little lower since they are way more efficient than a comparable holley, so a 750 holley would equate to a 650 demon and a 650 holley would equate to about a 625 demon which is what i am running right now
