Actually the centrifugal superchargers are generally easier to install because you don't have to replace the intake manifold like with TVS or Roots. I went procharger stage II because I wanted to be different from most of the other centri's who are running either paxton or vortech. I'd be careful with the Edelbrock. I've seen at least 2 people who have blown motors with that system installed. Regardless, invest in a solid tuner, whatever S/C you go with. Go with someone like Lund or AED who have tuned thousands of mustangs as the 5.0 engine is very sensitive when it comes to tunes.
