Swapping a SOHC 4.6L for a DOHC 4.6L
Hello, I have a 1999 F-150 Lariat 4x2 stepside with a SOHC 4.6L pushing 160,000 miles. It is a beautiful truck and I have had many people admire it or ask me if it is a HD model. Even people that don't care for Fords have told me that they like my truck.
The engine is running strong, but I have been eyeing the idea of swapping my SOHC for the DOHC 4.6L. I was looking at finding a wrecked Cobra Mustang with the supercharged 4.6L, but when I talked to the Ford technicians, they said that it would be a nightmare swapping due to the computer being setup for the car. They told me that it would be a better bet going with a Lincoln Navigator equipped with the DOHC 4.6L and then add an aftermarket supercharger, since the box would be closely tuned to my truck.
I have had people tell me to just get a 5.4L from the Lightning and slap it in, since it is the same truck. I don't want to be sucking gas everytime I touch the pedal and was told that the 4.6L is not too bad unless you get your foot into it. Granted, I will have the urge to get into it, but there are days when I am cruising the highway and would like to be getting a few more MPG's. I like that the DOHC 4.6L is a Hemi-style head with the huge valve covers.... plus, only a handfull or maybe nobody has one in an F-150.
My question here is this; does anyone know more information about the possibility of swapping the engines or know someone who has? I would like to gather up the information as to special parts, tools and such that I would have to take into account for the swap.
