If totally original--air horn, base plate, choke pull off, etc, I believe it s/b worth more than $1,500. The original pull offs for ram air engines were yellow. The pull offs were different colors for different applications. None of them were generic white as used on many restored carbs.

Having the original plastic fast idle cam in good condition is also worth extra. Most of these are generic metal on restored/rebuild carbs. Again, these fast idle plastic cams were different for different applications.

The number of totally original ram air carbs floating around is very small--most have been modified in one way or another or are restamp/Frankenstein units. I think a truly original one is worth much more. A 4-speed unit worth more than auto.

Sold in one day seems to say it all I suppose. A picture of the carb would be nice to see. As said, production dated carbs are worth the most since they are the only correct carbs for a given engine.
