Aluminum blocks when they go usually go in pieces.. I've seen a Aluminum block 5.7L blow up and when we took the oil pan off the lifters were in the pan along with a big 5" gap hole on the side of the block.... with a iron block you'll still will more then likely just need a rebuilt kit rather then a whole new engine setup starting from scratch..It's just a little more reassurance

Yup. Plus the cost is over $1k difference after all the parts add up. And the iron distributes the heat better, as well as has less cylinder wall distortion.
