whats your favorite diesel pickup

Just one engine out of em all? Jeez that's hard. but out of the 3 families listed, I'd take a Cummins. I honestly have thought of shoving a 4BT in a Dart. Honestly, I'm not a fan of the newer stuff. I like all the old weird stuff and the 12v 6BT. The new Cummins are cool, but new stuff doesn't strike my interest, diesel or gas.
