How do I identify the size of an Edelbrock card I think it is a 600 but want to make sure before I sell it
Homer-look at the number on the bottom at the front of the carb 'foot' where the front right(passenger side) mounting bolt is
If it says 1405-it is a manual choke 600 cfm
If it says 1406-it is a electric choke 600 cfm
