Well that kit isn't sold new anymore, so I couldn't find any good info on it quick. I think Vortech bought Paxton, so you might want to call them for info, maybe they can find some old instructions to send you before you buy it.
I'd think the install would be fairly straightforward. Like I said before though, you'd need to modify the piping to work with the newer engine layout. I think the install is actually simpler than my BBK kit, in which case fair game for a better-than-average wrenchhead, or a competent wrencher with time and patience. And it will cost you more than the cost of the unit due to the plumbing parts you'll need.
