Hey, sorry it took so long to write back. I decided to wait to put the engine in untill I got my Torque Monster headers. So first off this is a direct drop in. I didn't believe it since it's almost never that easy, but it is. Now I can't be completely fair and say it's got a huge amount more power because I am complaring it to a pre GT-40 P engine and I added the TMH's and a Mac catback exhaust and intake. As the truck is now it will snap your neck back.
Install wise it was cake, the engine comes with the wiring harness and all vacumm lines already attached. The only wiring you need to install is the starter wires and the harness for the AC pump and alternator. This engine does not have the oil level sensor, so if you have the info center in your center console either that feature will not work, or you will need to swap oil pans. I took the plenum off that way I could tip the engine back to make the tolp trans bolts easier to get too. Also, install the accessories with the engine in already. It will clear fully assembled, but it makes things alittle more difficult. The one and only difference that I found between the engines is that the throttle body on the Ford Racing engine does not have the nipple for the crank case vent tube that the truck came with. I havent decided what I'm gonna do with it yet, but I will probably route it to the air box.
One thing to note, if you intend on changing the motor mounts like I did get the OEM ones from the dealer. They arent stocked by Ford anymore but they can get them from some company in Wisconsin that buys up NOS stuff from dealers. Anchor engineering is the only company that makes them that I could find and they are built to only handle up to 75 ft-lbs of torque. Spec is 109, they snapped like twigs. You also have to remove the front axle assembly to get to the motor mount to frame bolts, so be prepared.
