I read that too, I have been reading alot about the 4.6 blocks due to my next car probably having one and from what i read they should work with different intake? I think, maybe i took it wrong.

heads/cams/intakes.

and i think possibly new cooling lines, and other mis items. its not a simple swap but its not too difficult either. i have been reading that issue an MMFF for a few weeks now.
