The real answer is WHY WOULD YOU EVEN BOTHER? Why would you put a 1200 lb low-rpm engine into a car designed to go fast and handle, at least a little?

If you're looking for fuel economy GET A DIFFERENT CAR!

The prices of any MOPAR muscle car have gone so high that to bastardize one with a Diesel engine makes no sense whatsoever. When you can't even get close to a decent E-body builder for less than $8,000, you tow your musclecar to wherever you need with your Cummins Diesel truck! Maybe, just maybe in an Imperial it would make sense. But there have got to be better Diesel engines for automotive use than that Cummins. And no musclecar deserves a smoker. Period.
