Of course because it was essentially a truck/van/station wagon engine. They put them in Dusters and Dart Sports because they needed 'something' to replace the 340 with to sell to the 'youth market'. Imagine if they went the opposite direction and tried to push the 318 instead? Logic says the 360 was the only choice in that situation, (thankfully) regardless of how toothless it was at the time.
Most Big 3 engines in the mid '70s were boat anchors, not just Chrysler products.
