Holley has made a bunch of changes to all of its DP series carbs over the years,some have internal modifications and some where external like on the linkage changes. Post which list # yours is including the dash # ,IE 4779,(first generation with no dash #) 4779-1,-2 thru -9, then we can look up the stock jetting and you can go from there.
