Default 99 Cobra - Ls3 conversion help

I have a 99 Cobra and I'm wanting to do a LS3 swap. Can anyone provide me with information on what all I'm going to need to change out. I know I'm going to need LS1 T56 Tranny and wiring Harness... Do I need a K-member? Do I need to run F-body or C5 headers? Are there any writeups on this conversion?

I don't know squat about this conversion but you may need a cutting torch and a welder.

I know a lot of fox body swaps have been done, not sure about the later Mustangs. Search around in here, I am sure you will find one. Sorry you wound up behind a wheel that says Ford, but at least you are looking to put a big-boy motor in! (Sorry, had to do it)

There are a million little thing sthat will add up. If you want a listing of some of the part numbers/cost/sources for some of the adapters and whatnot, please download our swap spreadsheet at: http://hosted.filefront.com/67rsss
