The only real advantage to an aluminum center section is a reduction in unsprung weight. Unless of course you use an aluminum 9" center section that accepts GM 12 bolt components.

Once again, we have bigger issues than this in the class, this is merely another minor distraction.

Do I think aluminum center sections should be legal? Not really, and certainly not if aluminum radiators and drive shafts are not legal for cars not originally equipped with them. Do I think aluminum center sections are a huge issue? Not really, so long as they are not the ones that accept 12 bolt parts.
