'99 Expedition Engine Swap
I have a '99 EXP XLT with a 5.4L in it, 172K miles with an oil leak coming out of the head gasket. About a $2K repair at the shop so I was figuring I'd just replace the motor if I found one. I found a 5.4 with 53K miles on it ($1250) in a 2005 F-150. How can I find out if this engine will fit in my Expedition or does anybody know? My VIN is 1FMPU18L5XLA30395, don't know the VIN of the F-150 other than the eighth digit which is a "5".
Thanks.
Thanks.

Thanks for the reply. What does the 'v' designate? Could you define everything other than the computer. I will have all of the accessories with this motor, just not sure on the computer part of it. Any idea if it's a plug and play kind of thing or might there be issues with the connectors and wiring harness?

2V vs. 3V means the # of valves in the head, per cylinder. The 1997-2003 F-150's had 2 Valves per cylinder (1 intake & 1 Exhaust). The 04 & newer 5.4's have 3 valves per cylinder. The whole top end of the engine is different. I know to swap, you would need the complete harness, computer, fuel supply, maybe adjustments to the exhaust, etc. It would be a pretty big undertaking unless you have access to a lot of Tech data for both models to figure out what can connect where.

97-98 engines were lower power.
99-03 engines were called Power Improved. They had about 30 more horsepower.
As far as I know, if you stay in the 99-03 range it should be a direct swap, 5.4L for 5.4L. There may be an occasional sensor change or connector change. If you can reuse your harness, the longblocks should be the same. I haven't done a swap yet (looks for wood to knock on...) My 99 Expi just went over 90K miles.
