Very nice Holley 770 cfm aluminum vac secondary carb. I ran it for a summer before switching to a mechanical secondary. Should be a bolt on and go. 4 corner idle mixture adjustment, dual sight glasses. I had the choke horn milled off for hood clearance on a 440 and an Edelbrock Performer RPM intake. $325 plus shipping or local pickup 100 miles straight east of the Twin Cities.
