i have a 02 f150 with 4.6 and it has the coil over the plugs and i am wanting to put a 99 4.6 in place of it but the 99 has fthe coil packs on the front of the motor. what will i have to do to make this swap . please help me. thanks

 

Use the COP system and you'll be fine.

 

sorry jbrew but i have no clue what that means. a little confused, the 99 has the plug wires and i dont think i can use the indivudial coild on this motor.

 

It means take the 99 coil packs off and discard them. Take your COPs off your current motor and put onto the 99. Then your current wiring harness will plug right into them

 

COP = CoilOverPlug

 

i just looked and no place to mount the cops on the 99 motor

 

You'll also have less power with a 99. It's NonPI. But you can use it .

 

You may want to let someone else swap this for you. - It's a easy swap, just need common sense.

 

lol i jprobally will but getting good deal on motor and want to make sure it will wk before buy it because it only has 81000 on it and my 02 has 230000 and just blew the second spark plug in 5 cyl.

 

Why don't you just fix the blowout properly? The only inserts that work permanently are Timesert - and if you blew an insert, you will probably need a BigSert. The other option are the guys at blownoutsparkplug.com.

They will stop blowing out if you install them correctly - no antiseize and 28 ft/lb torque.

 

i have already blown one out and this is the second one, plus it has some high miles and the heads are about 350 each plus the gaskets. looking at 1000 to replace the heads and gaskets and still hhave a 250,000 mile motor

 

Yea, you aren't going to be able to do this swap . You would need to use your intake and heads from your old engine or figure out a way to tap hold downs for the coils. That's all that's stopping yuh, - hold downs for the coils.

I would just get the heads fixed. You can rent a kit here, and fix it cheap. Without even removing the heads.

 

jbrew: is there anyway to use the 99 coils

 

Where are you located?? I have a set of PI heads that I'll sell you pretty cheap.
