What would I have to do to do this?

You already have a 'cammer'. Are you refering to the 5.0 4v? Probally lots of work, mostly in figuring out the wire harnesses. The mechanicals would probally be pretty simple. Personally, I'd do the 5.4 4V... I think Steeda is making an aluminum block (say it in a mag recently). You'd just need to get the cobra wiring harness/computer and hook it up.
 
contact FRPP. they use the cammer in the race car, and have about everything you need, but i hope you dont have inspections, because it will not pass.
