I don't know how to ID an Edelbrock, but I'll give you my "this is what I would do" advice. I would get an old Quadrajet from a 350ci GM and rekit it. Quad's have their number stamped on the side so you can get a kit everytime it needs it. I'm just a little partial to the Quad since they adjust and rebuild so easy.
Nice meeting you last week-end too!
