The decision is made

I actually reading stuff on it right now.. lots of talk with no body actually committing to it. I'd like to know if Carr's kit is bolt in ready or do I need to source out parts to make it work and can it hold up to 700-800 hp? Oh and cost, it is cheaper for me to get my 727 rebuilt, get a new TC, and then buy a Gear Vendor OD unit?
