Ok so I'm about to pull the trigger on a 4.6 out of 99 GT at a local salvage yard, but a "you pull it" type yard just got a 2001 Aviator with less than 100K on the odo on the lot this week. I can get the engine for 150, and the trans for another 125. Not sure how much of a bitch it is to pull this motor out of that truck but I'm willing to put the effort in. I've got my ducks in a row for the SOHC swap, but do I need to do anything different right off the bat for the DOHC? My 98 Cobra didn't have much room at all in the engine bay, and I'm just not sure if I'll need anything in addition to what I've currently procured for a SOHC swap.
