guy is selling a 4.6 crownvic motor dirt cheap and i was wonder what is the differance in these two 4.6L motors. is just the cams or what? will the crown vic motor fit in my 98 f150? if it does what will i need to make it work and run right?
thanks guys.

 

the intakes are different. knock sensor may be different, flywheel may be different. depends on years you are dealing with.your truck may be a romeo or windsor, the vic is most likely a romeo. few diffs, but easily overcome

 

well my truck 4.6Lis a romeo and the vic motor im not sure of, but i do know they look identical. looks like same cast intake and throtlebody. flywheel im not sure of. knock sensor? where's that located? thanks for the reply. i really appreciate it. so what im wondering is, are these identical other than what you mentioned or is there a mojor differance in these two motors? like i thought the trucks had different cams than the cars.

 

intake manifold and exhaust manifolds are different along with maybee the flywheel. if its a 6 or an 8 bolt

 

From what i have seen and read, the cams only changed when the pi heads were introduced. the intakes are completely different because they have a different parameter to work under: the truck is heavier, necessitating loger runners, promoting low and mid range torque production. knock sensor is in intake valley. main difference:some years are larger size threads, most people just swap the end of the connector. Make sure that vic motor is not too high mileage.also, let us know the year differences(yours and the vic) and we will be able to help more

i have a 98 vic and an 03 f150 can i take the 4.6 out of the vick and put it in the f150 to replace the 5.4

 

Why would you want to? It has a lot less power.
