Slightly heavier and a bit less power than the 6BT in the Rams. Aluminum block and head is an option, that would be well under 454 V8 weight, with 100 ft.lbs more torque at 1000rpm less
Was not really thinking of this for light truck or autos, but for 1 ton and up applications
Here for an example of a very civilized swap
Biggest problem that would be impossible to solve would be that yes, they are 'buzzy' at highway speeds and will pump out more soot, but they weren't shakers and rattlers like the 6.2
But it would give Diesels a great rep vs the 350 and 6.2 and 6.5. Not gutless, and will outlive the chassis the motor is mounted in.
