I just had to change the 4.6 in my truck. I used a $500 motor from the same yr crown vic just had strip the motor down to heads and block every thing else had to be used from my original truck motor. its not hard its mainly just a buch of small things. oil pan intake timing chain cover exhast manifolds (when you start taking those bolts out be prepared for a few to break you can get new ones at autozone for 6 bucks the worst is getting em out if they do break. best advise soak em in wd-40 for 2 0r 3 days then they break look real easy). also with the oil pan change the oil pick up tube will hafta be changeds across as well. the water and oil filter adapter will most likly hafta be changed as well. like i said just a bunch of little crap but it saved me an extra 1000 for a direct drop in motor. also when your moving all that stuff over while your there you might as well replace all the gaskets with new you dont whant to be having leaks after all that work. so in total in costed me another 300 for all the gaskets seals also made my life easy changed the plugs while the motor was out he he.
wished i would have had the money for a new power steering pump and headers while i was there my power steering is driving me nutz when its cold out.
also be shure when looking for the new motor its the Romeo or Windsor match to your truck closer to the same yr is better but there all the same year wise for the most part. so this can be identified by the 8th digit in your vin a W is a Romeo (i thought i had a windsor at first but nope ford got my hopes up then crushed it W is for Romeo) and i believe an 8 is a Windsor you can google it to be shure for windsor but i know for shure W is Romeo. the only real diffrence is the fact Romeo is 6 bolt main (more comon) Windsor is 8bolt main.
sorry for the long post i just wanted to give you as much info as i could think it. its alot of choices. Just a rule of thumb for the quickest easyest drop in go with the closet model and year possible. Cars do work just hafta swap out most of the exterior of the motor.
dont try and confuse me like that dang it i already have enough random crap going on up there LOL you made me google it
two seperate referances that says romeo has 6 Windsor has 8
2nd post down says the same things 6 bolt romeo 8 bolt Windsor
this one says you could be right too in the fact windsor supposably came with both yes i know it deals with 99 and up
Pic of my Romeo Block pulled I know its hard to see but i count 6 holes
i can also go out and take pictures of my 6 bolt romeo fly wheele that i have lying around
