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.
