Is it possible to buy the 00 Cobra R 5.4L Engine anywhere? Even from maybe ford? Anyone have any links/sites, etc. I know the 5.4L Triton V8 the F-150s used to have was a SOHC, was the Cobra 5.4L SOHC also or DOHC? I want to say it was DOHC because it was a cobra. Anyway, im not really interested in swapping to a 5.4, but it did peak my interest. Anyone know where to get one or how hard a swap would be?
