Only the BelAir had the bubble top and there were a total of 166,000 produced. Only 15,019 had the 409 engine. As to the exact number that were bubble top cars I am unable to get an answer I would be 100% sure of.

If you are asking about a bubble in a liquid, the answer is that the bubble has lower density (the gas inside is "lighter") than the surrounding liquid. If you are asking about a soap bubble, the answer is that air currents carry the bubble up. The bubble itself is not lighter than air (unless filled with another gas) but the film making the bubble is so thin and light that air currents can move it easily.
