Yes you can, but then you will need the proper flywheel or flexplate. The Ford Modular 4.6 engines are internally balanced.

I have the 8bt flywheel and the 4.6 motor with a 6bolt flywheel so I need an 8 bolt crankshaft right

30,395 Good information at the link. Not sure if you have a Romeo or Windsor engine. I failed to notice you were referring to a 4.6 in an F-150. My fault.

Bob Beaman
30,395 Romeo and Windsor There were two cranks used in these motors from ’99 through ’04 with a couple of variations. There’s a light one and a heavy one, depending on the year, and they had six or eight bolt crank flanges, depending on the application and the year. The Romeos always had a six-bolt flange, but the Windsors came both ways, so check the application charts to see when and where they were used.
