I guess this is a Stock? 4.6L engine as the vehicle was an ex-US Marshall Service surveillance and transportation vehicle. I added an eBay CAI to the engine and went to the drag races to see what it could do. As You can see from my signature, it moves.
Drivetrain:
Ford 8.8" rear-end with possibly 3.27 gears.
Notes:
I have rebuilt the entire front-end with new super duty joints and Energy Suspension bushings. I am slowly rebuilding this car for the long term. I intend to keep this as my last vehicle (or until I can get a Cobra. :-))
