I like the Aluminum ones for the way they fit & don't leak, but some like the steel chrome pans because they say they cool better..? I have a steel one on the 400 th. behind a 455 Buick ( yes the Hemi Killer!) in a 40 Buick coupe.I have a Derale Cooler hooked to it & have had NO heating problems, even when doing a lot of burnouts.

I have most popular pans in steel or Aluminum.
