Hugh, it is VERY simple and you will immediately see what needs to be done.
-There is a locating pin that needs to be ground off that helped locate the intake over the runners (not necessary if you very carefully line up the bolt holes and then snug one down so the intake doesn't shift.
-There is one/two fins on the rear of the intake (opposite the actual throttle body) that need to be clearanced.
-There is a portion of the rear passenger side of the intake that, when flipped, comes in contact with the coolant outlet casting on the top front of the motor. This is the most nerve-wracking one because you actually have to take down some of the thickness of the body of the intake- not just useless flash. This took me the most time and numerous test-fits. Remember too that the housing will grow when the engine is warm, and leave extra clearance.
I was worried about what the flip entailed, and I ended up finishing the work in a few hours even while being extremely careful to clean everything extensively between each test fit. I have NOT pulled apart the harness to move the throttle body plugs to the rear of the engine, which supposedly requires a wire extension to be soldered in. Physically, the operation is simple. I can post some pictures later tonight.
Having had a 2012 GT with the Coyote, I am pretty smitten with the motor. Compare it with prices for LS engines, and it is ridiculously cheap, durable, and modern plug and play stuff for kit cars.
