1405 or 1406 edelbrock carb

A dead bone stock 318 can use a 500 cfm carb. (Hwy. geared like car.)

OOTB carbs are a no touch deal for the electric choke. There all ready set. They do or at least should include tips for adjusting it or resetting it , but I have never needed to mess with them from and brand of carb maker.
