Question for those running a 500 cfm Edelbrock

a 500 avs is almost self adjusting the valve on the secondary side wont open till the engine pulls enough air to open it the factory jetting will be close for wide open throttle. the tuning issue will be for snapping the throttle hesitations things like that. use lots of initial timing will help.leaner jetting doesn't make the carb smaller it makes leaner. usally carbs that are larger then whats considered to be normal use run lean at lower rpms because of low air speed causing poor mixing but when engine speed climbs the air speed picks up to exceptable speeds and fixes the problem. basically i wouldnt do much till you have good feedback like driveabilty and reading plugs that is of course that the carb is starting off a stock piece
