Mopar Mistake 'Not offering a 273 Commando HP II 'option'

That would have been cool for sure. I was disappointed to hear of the lower HP rating of the 4 barrel 273 but I'll bet the manufacturers didn't dyno anything back then. The little 273 has potential with the right parts and tune. I think the exhaust is the biggest downfall. If they would have built the bodies a inch or so wider, there would be room for better manifolds or easier to install headers. Mike
