Ford kills Boss engine for F-150, Mustang
 

The powerful V8 engine was slated to appear on models ranging from the new Mustang to the best-selling F-150 and Super Dudy, but a stop work order has narrowed the Boss' available engine bays down to one model. Ford President of the Americas Mark Fields told Levine that while the program isn't being killed completely, it will now only appear in one vehicle. Levine has heard from three sources that the lone vehicle will be the Super Duty, which needs a more efficient replacement for the 6.8L V10. Ford has already spent a load of cash on the beefy pushrod, so killing the program altogether would have been a tough pill to swallow. Ford was also planning on more than one displacement for the Boss, but with it now only going in the Super Duty, it'll likely only appear in 6.2-liter guise.
