I had a old 79 Dodge class c with a 440, it doesn't matter what the old carb had for choke just get a new one that has the electric choke and run a new wire if it does not have one, its a easy fix, you can tell a manual choke by a small linkage that goes from manifold to carb that has a metal sprail attached to linkage.
Yes that Edelbrock is a good carb.
