There are different versions of this truck. The 4x4. the lowered Super Snake, and the unaspirated version and it seems some of time times and comments are based on different versions. The current version, with 4wd, is rated at 0-60 in 3.45. I have the 700hp supercharged 2016 version that is rated, and I can attest to, 4.5 sec 0-60. It is a fast truck. The 2 times I have let myself go with a Raptor at the line I have won handily, no idea which version of the Raptor, and I love the Raptors, great trucks. Yes, Tuscany Motors in Elkhard, ID builds the trucks, that is their specialization. They give good support. Shelby American, which I live very closely to and go there often, build the GT350s and GT500s as mentioned. They are tapped and Trucks are not their forte, so they license Tuscany, smartly since they are not truck experts like Tuscany. Tuscany does much more than listed. When I needed info for my truck Shelby gave me what they could but directed me to Tuscany, who were awesome. All modifications done by Tuscany approved and licensed by Shelby American. True that Shelby has put its name on some things in the past that were not up to Shelby levels we all would want, but it seems they quickly learned and moved on, we are in year 6 of the F-150 Shelby and it is a bad ass truck from someone who own one. Shelby F-150s are sold new at Ford dealerships, so they are affiliated with Ford at least in that way. I also own a 427 S/C Cobra replica made by Superformace and licensed by Shelby and quite happy with that as well, I did not want a kit or a non-Shelby Cobra and couldn't afford the $2.5m+ for one of the remaining 29-31 originals. I would not steer clear. I could sell mine for more than I paid in 2017 (used), they do go down in value from new, but hold pretty well in the $60k plus region depending on condition and mileage.
