They are both Holley GM Musclecar carbs Carb # 3310 GM # 3878261-EH carb that flow 780 cfm from the factory thanks to the downleg boosters. These would be a nice upgrade for modern 3310 carbs for more airflow. They have no choke. Date codes are 035 = 1970, March 5th week. and 973 = 1969, July 3rd week Do your own research. Dirty. Needs to be rebuilt. This GM part number came on Chevy Musclecars. When you rebuild this carb, if you take it apart and find something missing…please contact me. I have lots of Holley parts. I will be happy to send any missing internal parts you need. Thank You.** Parts have been sitting for a while and are dirty and need to be cleaned and rebuilt. Yet the seller (that's me) has nothing to do with that and cannot make it mandatory.
