All this talk of truck and passenger car engines is funny. Chrysler Australia took a "truck engine" that was designed in the US but not used because they needed a replacement for the slant 6. They needed a performance version so they sent one to Italy to have the Italians design the induction system and stuck it in a short wheel base A body and ran 14.1's in the quarter in the early 70's with a 265 ci inline 6. Not bad for a "truck engine"
