I have 2 Carter carbs and 2 strip kits for sale.The carbs are both numbered 3721 sa. One with manual choke has d4 under the 3721sa number. Other has k4 under the 3721sa number. I ran the carb with the choke for years on a 283 sbc.The other i bought and have not run.it was painted gold by previous owner(no clue why) Both carbs will need kits im sure. I bought second carb to use on tunnel ram but went with holleys.The strip kits I bought used but look to be pretty complete.Please note where fuel inlets are on carbs.one on front left corner and the other on back left corner. The carb without choke ***embly may need a heli coil for vac. advance port. If you have ?s please pm. Asking 300 for all plus the ride.
