One of the items that comes up in discussions of truch tech is the engine block. Lots of smaller vehicles have aluminum blocks, and don't seem to have a problem. The F-150 still has a cast iron block, but the Titan has an aluminum block, and I assume so does the Armada. On a large V-8, such as you'd want for a large SUV or half ton pickup, what's the weight saving by going to aluminum for the engine block? Is there really a weight savings? Do any large American SUVs or P/U use them, or is this another place where Detroit follows only after Tokyo's there?
