WHO’S GONNA BE THE 1st TO DO THE SWAP

I should have said that better. I was asking about motors designed and produced after 1971 (just a random date I pulled out of the air). Wasn't even limiting it to Mopars. Just trying to gauge whether there was anything you like that was designed after Nixon was in office.

EDIT - I'm not asking about what you would swap into an old car. Motor swaps are not part of the question.

Not necessarily 'designed' but more refined would definitely be the 5.2 and 5.9 Magnums.
