Upper intake manifold

I need to know if the intake manifold for a v8 4.6 will fit and operate the same as an intake from a v8 5.4 my engine is the 5.4

Go to RockAuto and see if the part numbers are the same.

I did but the part looks different even with the same part number

Post links to the two parts, we’ll check it out.

and the part that was on is cracked and couldn’t find a link to the part …i appreciate the help the part that is broke is pictured in the post

This won’t work. The 4.6 manifold is narrower than the 5.4. The ports won’t even be close to lining up.

Here’s a brief video showing the modification of an aftermarket 4.6 carburetor manifold to fit a 5.4.
