As a thank you to this forum for the all the free information found here that i used to do this swap, i am posting this write up for others to use.
The following post is not to be taken as advice from an educated mechanic. If you notice that i have done something in a way that i should not have, I am open to constructive criticism. If I make a statement that is untrue, please correct me so that i can fix it so the info people find is all good. just keep in mind i did this with hand tools only. no air, no power. and not as a flex either, im right in the middle of starting my life over again and just doing what i have to do to get my **** together.

To anyone out there searching that finds this looking for an inexpensive option to swap out their 4.6 2v after a broken timing chain and major engine damage,

YES, If You have a W in the 8th digit in your vin, (Romeo), You can take a 4.6 2v engine from a crown vic Police Interceptor or any of the other ford lincoln mercury vehicles that have the 4.6 2v as long as they are also a Romeo engine.

Im sure someone out there could do a windsor/romeo swap but if you want to minimize difficulty, find a romeo.

I bought a 2004 f150 heritage 4x4 that had a broken timing chain for a few hundred thinking, Man, if i can fix this, i can probably flip it for a bit over 2 grand.

ive only done timing on little cars that werent interference engines and didnt realize the amount of damage that occurs when it breaks.
It looked like a glitter bomb had gone off in the oil pan and there was sparkly sludge and unidentifiable pieces of metal and plastic on every surface inside the engine.

To skip all the boring parts, i found a guy that had recently pulled an engine with the trans out of an 06 Crown Vic Police Interceptor and only used the transmission.
Picked it up for 400 complete from flexplate to belt and even had the injectors and plugs.

Basically, you have to strip down this new engine all the way to Block and Heads. leave all internal parts alone, they are identical to yours.
You must remove and replace all of the following with the parts from your trucks engine:
Throttle Body/Intake/the whole vacuum line setup

Left-F150, Right CVPI Notice different size throttle body hold

Left-F150, right-CVPI Identical manifold gasket on the bottom.

The metal tube that runs under the intake to the Heater Core
Exhaust Manifolds

Left-F150 Tensioner mounts in a different location and swings a different direction. same gaskets, same bolt hole locations

Belt tensioner
Alternator, (i bet it would work though if you changed the plug on your harness)

Left-CVPI Different plugs, f150 has two connectors and the big power wire, CVPI has one connector and the big power wire.

WATER PUMP, (This was my biggest mistake. Your cooling fan screws into the front of your water pump. The Cop car had electric fans with no place to screw your fan into.)

CVPI had electric fans

F150 no electric fans but your fan with screw on and you wont have to decide between tearing it apart to replace the pump or rigging up some fans on a switch....

Motor Mounts

Top-F150,

Oil Filter Adapter

Left-CVPI same gasket as the F150 but a lot more going on

left CVPI for some reason the CVPI filter adapter has a more restricted coolant flow than the truck

Fuel Rail
Im sure im forgetting something so if you have a question about it please just hit me up and ill be happy to help you figure it out, i didnt take very many pics early on besides the ones to my buddy saying, "Look how ********** this is, Bro!" When i decided to swap i took pics of everything that was different. So if you would like more pics i might have some of what you want.

I read other posts where it was stated that your oil pan must be swapped, that is incorrect. the only difference is the drain plug is located opposite yours. On my truck it was on the passenger side and the CVPI engine has it on the drivers side of the oil pan. I went with it and it has almost the same amount of clear space around it as the old one. there wont be issues during oilchange.
I also have seen it stated that the valve covers must be changed, also incorrect, they are identical. the only difference is the style of connector for the pcv hoses and i just cannibalized the new connectors onto my hoses.
For the numbers people heres the stickers on the valve covers, the two digit ones on the rear had PO on the CVPI, and 67 on the truck

Top-F150

The Flexplate looks different only because of the extra holes drilled for what i assume is balancing purposes.
I struggled with lining up the Flexplate/Torque Converter bolts more than anything else in this whole process.
The gear teeth and the bolt holes on the Flexplates are identical, the issue is that the CVPI TC uses the four holes that are just slightly closer to center than the f150. I dont know why, it just is and it took 2 days of after work struggle sessions and pulling the engine back out to learn this.

CVPI look close and you see the bolts were using the holes that are sitting at 12, 3, 6, and 9 in this pic.

F150 you can see the discoloration where the bolts used the holes at 12, 3, 6, and 9 in this pic. Notice the difference?


Well, It is very late and i have to be at work early in the morning so i will go ahead and post to see if theres other info anyone wants besides what i have planned.
Really any input is welcome, even if all you have is talking S*** and giving me a hard time, just dont get sore when you see the comeback.
To be Continued tomorrow....

 

Kudos for the success but especially for the writeup!
Some with larger engines are going to elec fans to save what appears to be SEVeral HP!!!
So, you used a DOGC PI? You have a mini-Lightning/Raptor?!? Hahahahaha!!!
