Welcome phithebuilder,
You'll find that it will be some work to get it to all fit in a cobra, but it is possible.
I know of atleast 1 spf that has a 5.4 supercharged engine in Aus.
I saw it when it was being fitted out.
Coincidently it is now for sale in Aus, but that's no good to you.

I believe similar packages have been fit into FFR & Backdraft cobras.
While their are differences b/w the aforementioned kits, they will all give you heaps of thrills, its just a matter of which you wish to choose.
...and their will be limitless discussion about which is better and why.
Best wishes,
