4v 5.4dohc > 3v 4.6
But it is understandable what you are saying Pat. I would rather just buy a V6 rip the motor out and throw in the huge ass Roush 427r in it and redo the suspension and call it a day lol.
Then again if Shelby kicked the bucket ther would be some peopel out there sitting on a few extra bucks lol.
