If you planned on cams, heads, poweradder, etc then yes but to just use as a stock replacement with more discplacment than no. They are rated the same Hp wise but have more torque...I also believe you need a new hood due to the extra deck height plus to run the PI intake you need the intake adapters....
If someone is looking for a project then sure but it's just easier to stick with the 4.6l...in my humble opinion.
