Great! Before I would start something like this, I would meet with a tuner/builder (like Hennessey mentioned above, or others). I would outline my target HP goal, and then build a strategy to achieve it holistically as opposed to a popcorn approach where you may be doing things that are not needed, or circumvent other items you add. In other words...get an A-Z plan/strategy so you can be efficient as cost effective with your build...And meet your target!

Since this platform is scarce on info related to this, I might consider a Mustang specialty... as they are familiar with Supercharged 5.0 L V-8s

Good luck.
