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

 

there is an id tag on one of the valve pan covers with a number on it. I don't know how to decode it though. Went through this when I bought my motor
