Even though a 3130 is not a Z-16 Chevelle carb, it is off a 425 horsepower 65 full size Chevrolet and still relatively valuable, especially if it has the 65 only small inlet fuel/float bowls. Just by looking at a picture, the 1965 Holley 3310, 3130 and 3124 all look almost identical. I will attach a picture if a "real" 3310 carb for you so you can see the float bowls I am talking about.
