11" X 3" drums were used on both the front and rear depending on year/model.

my 70 sport fury (originally 383 2bbl power drums) had them on the front. Converted to 73 discs now

Don't confuse different properties of materials which may or may not be advantageous in certain situations.
Aluminum has a high strength-to weight ratio, so is good for applications that need strength at a minimum weight penalty (aircraft fuselage, wings, etc.)
Aluminum has good heat TRANSFER properties, which make it good for automotive radiators.
Aluminum has nearly double (at approx. 900 Joules/Kg-deg K) the heat CAPACITY of iron (at 473 Joules/KG-deg K) by weight. But, at a little over half the density of iron, makes it slightly poorer as a store of heat than aluminum. By VOLUME, aluminum has a heat capacity of 2.43 Joules/cubic cm-deg K, versus 2.48 Joules/cubic cm-deg K, giving iron the slight advantage in heat storage per cubic centimeter.
In a brake application, heat builds up rapidly and dissipates slowly, therefore heat capacity is a more important property than heat transfer. That's why aircraft brakes are made from steel, stainless steel, carbon, and probably other materials also, but not aluminum.

I bought a complete set of 11x3 drums. I thought about putting them on my Duster. I was told it would be a bad thing to do with that small of a car. But maybe if I did Viper rotors on the front?
