Oh heck, consult with MartyO. Thinking I would be leaning towards a 6r80 with the coyote motor. Love my Circle D 3k stall with my mildly modded stock motor and transmission - your results may vary! Marty-Jeff-Eric nailed it down perfectly. Great fuel mileage at the moment while being used as a daily driver - about to park Marauder as Mustang is coming up for daily driver rotation.

“You've gotta dance like there's nobody watching,
Love like you'll never be hurt,
Sing like there's nobody listening,
And live like it's heaven on earth.”
