72 fitment aluminum radiator into a 1974?

The claims you're making about 2 vs 3 row radiators in general are false. Period. It is absolutely possible for a 3 row radiator to cool better than a 2 row, and be more efficient. Efficiency is also determined scientifically, there's an equation for that. The blanket statements you've made in several threads not are not accurate.

Our claim is that 2 big row aluminum cools better than 3 5/8" rows in aluminum. The claim is generally true. Not generally false. While there are other factors like (air flow and engine hp) that could make this claim false, the claim is generally true. We have done engine testing on radiators with 2 big row vs 3 small row, tri-flow, dual flow, same side inlet, crossflow etc changing only the radiator that 'generally' support our claims but the best proof I can offer is that of aluminum 3 row customers switching to 2 Big rows and experiencing lower temperatures. This is public information by real people found all over the internet.
1. A 3 row 5/8" aluminum radiator doesn't hold as much fluid as a big 2 row.

2. The flow of air through the radiator is restricted by the thickness of the radiator and the friction produced between each row.

3. Because the surface area of the tubes are smaller, the transfer of heat is not as efficient as the transfer of heat of the larger tube surface area of the big 2 row.

All of this is comparing aluminum to aluminum.
