I wish they'd bring back the V-10 Excursion. Mine's getting long in the tooth, and I'd buy another one in a heartbeat.
Ford (or any major automaker for that matter) will never build such a truck again. You can thank our all knowing, know better then you, federal government for that.
The only way you could have something like it, is to buy a 250-450 series pickup and have a custom shop build it for you. Bring cash, lots of it.
At this point, I will be surprised if Ford offers a V-8 engine in ANYTHING in a decade. The 150 series pickup is now an aluminum bodied 2.0 liter V-6 turbo! Only one V-8 engine choice left, and I doubt it will last more then a couple of years. CAFE is breathing down their necks, and Ford sells far more pickups then electric Focuses.
The upcoming GT will not offer a V-8 at all. Neither will the incoming Lincoln Continental. Once they can sell enough Mustangs with turbo 4's and V-6's that 8 will be history. I bet if they build that bronco and ranger they will be aluminum too, the top engine will be no more then that 2.0 turbo V-6. More likely turbo 4's.
Even V-6's will be rare and pricey, and sooner then you think. We are coming into another era of overweight underpowered vehicles.
