I found some toys...
 

Last night I was looking for a tool and stumbled upon a box in my garage with 4 carbs in it. I was wondering which if any would be an upgrade over stock and what I should ask for them if I want to sell. Here are the #'s I found on them (I hope they are helpful in identifying them):

Holley 2100
Holley L6503 2807
(2) Solex 34 PICT-3

Thanks for the help fellas. Happy Thanksgiving!!
