New Edelbrock AVS 800cfm carb and calibration kit

I have a new Edelbrock 1813 Thunder series AVS 800cfm, electric choke carb for sale. It was bolted on my engine and sat there for about 5 years. Other than being a little dusty its like new, never saw any fuel. I do not have original box for carb. I also have complete calibration kit that goes with it. I took the plunge and went fuel injection so dont need this now. Retail on carb is $453 and the kit is $71. Asking $425 plus shipping.
