If you've watched power block a couple weekends ago, horsepower installed the supercharger on one. The power output is real close to that of the supercharged 5.4l in the 2011 GT500. Problem is, a 5.4l crate engine is $20k! The 5.0 crate motor is only $8.7k, add another 6k for a kenne bell and for $5k less you will have the same power. I'm really considering a 5.0 coyote for my 77 bronco's power plant when I build/restore it...
