Going In-Depth With Ford's Twin-Turbocharged V6 EcoBoost Engine

As quoting from this article: Motor Authority » Ford suspends Boss V8 program

"If it survives, the new Boss engine is likely to appear in the 2010 redesigned Mustang and could be downsized to just 5.0L in displacement."

I doubt that it's going to come back to life...

I doubt they'd down size the Boss engine to 5.0 since that engine would be a dog on the street w/ such a short stroke. For 5.0L, Ford can already do that w/ their Mod engine by using a 3.7" bore. However, w/ Hemis and 6.2L Camaros, Ford isn't going to do much when their GT500 w/ a supercharged 5.4 makes only a bit more power than those other engines. Ford needs the 6.2L Boss to compete. It may be a short run but it will be a blast (especially w/ 4V heads).
