I had this done yesterday, but photobucket was locking up my computer. When you get done reading this post, you'll know why
I got my mustang motor from the storage unit and started tearing into it down to the long block. There's enough detail for anyone wanting to know what is involved in converting a roller motor to use the explorer's electronics. I'm not concerned with gaskets at this point as this is just a mockup, later the motor will get a refresh/rebuild. Shane, PM me if your interested in some mustang engine parts. On with the pics...
Here is the motor straight from storage....
The upper intake removed...
The front fead off, Also a good look at a brand new water pump never run, just mounted..
Back side of the pump, still looks new short of some surface rust...
Timing cover...
Pulling the harmonic balancer using a Matco puller....
Balancer off....
Timing cover off...
Lower intake off....
Bottom side of stock intake, 120k miles...
GT40 intake going on the motor..
The cam syncronizer in place, well below the supercharger adapter mount...
Here is the difference in the timing covers, the mustang on the left, the explorer on the right. Notice the mustang doesn't have the provision to mount the crank sensor...
The driver side explorer fead bracket mounted...
The passenger side fead. All the mounting bolts are not in this bracket, as I don't have them. I had to dig out a bolt that would hold it in place. I'll have to source them later...
Fuel injectors installed, make sure to lubricate the O-rings when you install them...
Fuel rails installed. Again, make sure to lubricate the O-rings....
Here I'm using a 2x4 as a spacer to fab the adapter. Notice the fuel rail purge valve? It's the only part that extends higher than the fuel rails. I'm thinking of a custom fuel rail with the shrader valve in a different location so I can mount the supercharger lower...
The supercharger mocked in place using a 4x4 (3.5" high), here is the belt routing....
Side view, notice the fuel shrader valve..
The back of the supercharger location on the motor. Looks like I will have plenty of room between the back of the monsterous lung and the firewall...
Here is the height from the top of the lower intake, its about 9.5"...
Here is the GT40 upper mounted on the lower intake for comparison...
It's hard to see, but the top of the GT40 upper is right at 8", so the supercharger setup is only 1.5" higher than the stock setup, allowing me stealthness by keeping the stock hood
The other side the M122, notice the location of the fuel regulator. The fpr sits even higher than the shrader valve, but the M122 just does clear the fpr, allowing a lower mounting height....
Here is the back of the M122 in relation to the back of the motor....
This is the M122 sitting 2.75" off the intake, this is about as low as I can go, notice the shrader valve. If I either get or fab custom fuel rails, I can lower it even more...
So here it is. I'm going to look into different fuel rails as I'd like to get this a little lower. I have quite a few vacuum ports on the supercharger to either use or block off. All the ports you see on the M122 are before the rotors, so they don't see boost at any time. The ones that won't get used will get the port adapters removed, tapped and plugged. There is a port on the rear of the charger, this will be used for the pcv valve since its right over it. I'm not running EGR on the motor in my Trac, and since its deleted from the ecu via programming, I'll most likely tap and plug the EGR port as well. Onto starting the mounting adapter

Welcome Visitor! Please take a few seconds and 
I like to show attention to detail just in case someone else wants to use or need my photos for guidance, or entertainment 
I'll give you a couple of pics to look at, and here is what I'll be swapping the GT40 for...
