Hello and welcome to the club. A “half coyote” swap is what I’ve dubbed it. I am keeping the original style 6.5L 390 FE engine but using the Automatic transmission typical found in 5.0L Mustangs or F-150 trucks from 2011 to 2017. I.e. the 6 speed 6R80. Check out the “Speed Shop” section for full Coyote swap reference.
