Performance would be the same with either, both would require some extensive porting along with carburetor mods to supply the needs of a 600 horsepower engine.

Of course there would be a weight savings with the aluminum of around 15 to 20 pounds. A factory iron intake tips the scales at 38 pounds.

Mild 428 with 600 horsepower? A bit far away from mild I’d say.
