4.6 V8 interchangability question

I know nothing about these 4.6 engines, but I have a totalled 96 Mustang GT with a good engine, and I know someone with a 97 F150 with the 4.6, and he needs an engine. My question is, do these engines interchange? Are there any real differences between a Mustang and truck engine? I'd guess the timing chain cover, fuel injection/intake, and the oil pan would be different, but how about the basic long block itself? If I sell this engine to him for the pickup, will he run into any problems installing it?

Thanks for the help.

If he's got a Windsor 4.6L in it,it's still not a bad swap,and most everything will swap right over off of the Windsor engine.

Did you say you used to rebuild the 4.6 windsor?
I am going to rebuild mine soon and was wondering if you ran into any specific issues with them.
Is there anything to watch out for?
Anything unusual?

thanks

Windsor vs Romeo:
Rods:
Winsor-full floating pins
Romeo-press fit pins

Blocks:
Windsor-dowels for main cap alignment
Romeo-jack screws for main cap alignment
Windsor has larger front cover bolts than a Romeo

Pistons:
Windsor and Romeo have different dish sizes due to the combustion chamber sizes of the cylinder heads.

There are alot more little differences,but those are enough to know that they are NOT the same.
