The transmissions are different between the 5.9 and the 4.7. The wiring harness and computer are also different between the two drivetrains, and if the 4.7 is anything like the 5.7 as far as motor mounts, they are also different between the 5.9 and the 5.7.
We swapped a 5.7 into an old car that had a 5.9 and we had to change everything, nothing interchanged. Gene
