Easiest way is to look at the list number. Most types of 4bbl Holleys have them on the front of the airhorn (where the choke butterfly is) when you take off the air cleaner. Come back here with that number, or google it.

1850... 80451... 3310... 80508... 4776... 4777... 4778... 4779... 4780... 4781...
