I have a 98 F150 with 4.6, vin # 1FTZX1760WKB71976, and motor has to be replaced.
I found a 2000 Expedition 4.6, vin # 1FMRU1567YLA50303.
Been told that either could have a 6 bolt or 8bolt flywheel. Is there anyway to tell without dropping the motor 1st?
I dont want to buy the Expedition motor then find out that the flywheel wont match up.

Thanks

 

You're bumming BigWill. From everything I've read, there's no way to know without actually checking. I went to autozone.com AutoZone Auto Parts Stores | Get In The Zone! | AutoZone.com and sure as you know what, they show a six and eight bolt flexplate choice for both trucks. On the bright side, if they're both autos, or both manuals, it shouldn't matter. Make sure you get the flexplate/flywheel with the other engine and use it. I've also read that most of the Windsors where six bolt, don't know how true this is.

 

Just get the flywheel with the replacement motor.
As long as both vehicles have the same transmission, you ought to be ok.

 

Both motors came from the Windsor plant. You are good to go. Also, if you do run into a problem. It will cost about 250 for a "streamlined" flywheel where Ford has eliminated all these others and went to one that that has 12 holes in it, but they all line up either way. I went from a Romeo 4.6 to a Windsor 5.4L so your good. It may just cost you a little.

 

I have a 1997 f150 with a 4.6 windsor motor
