Will a 4.6 W interchange with a 4.6 6
 

I have a 97 F150 4x4 Extended Cab with a 4.6W Auto, and just picked 97 F150 4x4 with a 4.6 6 (I am guessing as there is no W in the Vin Number) Standard. The motor in this wrecked truck runs great was wondering if this motor will interchange with a 4.6W, or what do I have to do to make it work, since I have the other truck I have all the parts.

yes.

Sweet, is there anything that id different that I would need to switch or would it pretty much bolt right up?

does it have the valve covers on the "new" engine, thats the only diff. as long as they are there you are good to go.

I think the flywheel might be different, but don't quote me on that.

I would have to switch the fly wheel anyways as the parts truck is standard and my truck is a automatic, unless the bolt pattern is different.
