OEM 360 High rise intake?? Police/FBI-worth?

I was at my hideout yesterday of a salvage yard and the guy showed me an intake that he said wwas for a 360 FBI car. It still had the huge thermoquad on it and the intake looked like it was a hi rise style intake. It looked stock from what I could see. Couldnt tell if it was a single plane or dual plane but it was a tall intake. How much would this be worth-roughly- a guesstimate. He had that and an aspen?? R/T that was still mostly together. The carb was still all working-nothing stuck or rusted up. Sat inside a car for awhile, but not hooked up.
