3.5 HO is far more expensive than the 5.0. You can get a 5.0 in any F-150 down to an XL, the 3.5 HO is exclusive to Raptor and '19-'20 Limited models.I’m sure it’s been mentioned her, but a 5.0 in a Raptor would make the truck too expensive. Although it’s a V6 twin turbo eco boost, it still produces a lot of power. Especially if properly tuned with added mods such as exhaust, upgraded Intercooler etc. It already has a lot of torque.
