All the Hemi engines are still cast iron block/aluminum heads, even the lowest-powered 5.7. Its a little deceiving because the engine isn't *that* much heavier than an aluminum engine of comparable power (ie, comparing a 5.7 Hemi to the comparable GM all-aluminum V8s.) Nodular cast iron is strong so the castings can be thin, and casting tech has come a long way since the days when big-block v8s tipped the scales at over 700 lbs. The Pentastar v6 is all-aluminum as was the previous 3.5L v6, so its not like Chrysler flat out won't build aluminum blocks, but they still pour a lot of iron in their foundries compared to GM. Aren't most of the Ford modular blocks iron, or did that end with the introduction of the Coyote?
