Was the 4.7 the only iron block Toyota V8? I seem to remember that when the first gen Tundra came out, Toyota decided to give it an iron block engine for "perceived" durability by the typical pickup buyer. That's probably the reason it was replaced by the alum. 4.6 as now aluminum blocks are pretty much the rule.
