Guys, I'm looking for a coyote for a swap I'm doing and found this place and thought what better place to ask. I have been finding engines but they say: 5.0L (VIN F, 8th digit), from 01/04/13 or 5.0L (VIN F, 8th digit), thru 01/03/13. I'm trying to find how the before 2013 differ from the thru 2013. Any help would be great, Thanks.

 

The before '13s are 412hp and the 13-14s are 420hp. The 8hp is probably done thru programming of the PCM.
