Fact or Myth? LS Efi swapped onto 5.9/5.2 engines

Not sure if it was drunkin internet surfing or what but I could have sworn that at one point I found a link on the interweb that LS efi engine management can easily be swapped over to the Magnum platforms? :poke:

Maybe its wishful thinking but if you have heard of this or have any info or links to it being done please post up, cause now when googling or searching sober I cant find ****...lol
:wtf:

Thanks
