This will definitely make me pick up a LS with a blow engine and find a donor car.... You are defying the law of physics... everyone said that the 4.6 would never fit!
who said that?
Ford would have built the LS with a 4.6 had it fit in from the bottom, which it does not.
fits fine from the top.
Ford raced a LS with a 4.6 in it for a time as well.

i believe the real issue was getting the stock PCM to run the engine.
since everything is so integrated, much of the car is dead without the PCM.
