IMO, I would install stock copper rad, fan, shroud and A/C filler panels. Stock parts work and don't change the original sound of your car. If you enjoy the sound of a big block Pontiac stick with stock. I have an electric fan on my 455 in my motor home. All you can here is that bloody fan. It's huge as well. A properly designed aluminum rad with fan and shroud will work but you need one that fits your car's engine. And again, you stuck with noisy electric fan.
