Ford Triton 4.6/5.4 2v v8 differences?

So I was wondering if there are any differences other than size and power between the Triton 4.6 2v and 5.4 2v I'm thinking about swapping a 5.4 in my f150 its a remanufactured 5.4 long block and I'm wondering if I can transfer any of my stuff off my 4.6 to the 5.4 such as exhaust manifolds, intake manifolds, valve covers, pulleys, water/oil pumps, fuel rails, other stuff? Doing as much research as possible.

The 5.4 SUCKS *** the 4.6 is more reliable especially when it comes to the 3 valve 5.4 the smaller 4.6 and the 5.4 look similar in design but the 4.6 had nothing like the 5.4 boat anchor motor did thats why it was discontinued and is now the 5.0 AGAIN

They are the same engine, the 5.4 is just a bit 'larger' inside. There isn't much to gain by that swap, unless the 4.6 is trashed. So save your $$$ for a set of Trick Flow two valve heads…

For the 1999-2003 P.I. 2 valves, the 5.4L got you about 30 more HP but a whooping 50-60 lb/ft of torque. It's a noticeable difference in performance. The main difference between the 4.6L and 5.4L is that the 5.4L has a longer stroke, everything else is pretty much the same.

Depends if your 4.6L is Romeo or Windsor. All 2 valve 5.4L are Windsors, if your 4.6L is also a Windsor then most everything can be swapped over, if you have a Romeo 4.6L, then not everything can be swapped over.

I'm not sure what "?" is going on about the 2 valve 4.6L and 5.4L are about the same in terms or reliability the on thing issue that the 5.4L had was the early non-P.I. 5.4's had piston slap issue that while annoying, wasn't a huge deal, and was generally rectified when the P.I. Engines came out

"design but the 4.6 had nothing like the 5.4 boat anchor motor did thats why it was discontinued and is now the 5.0 AGAIN "

Oh my. The 4.6L and 5.4L are about as closely related as you can get with engines, they share the same architecture and share many of the same parts, they were also made on the same assembly line, buy the same people. The 5.0L Coyote is replacement for *both* the 4.6L and 5.4L, The Coyote is also consider a modular engine and shares several design features with the prior 4.6L and 5.4L engines, it's an evolutionary design. It's very similar to the 4 valve 4.6L/5.4L with the VCT from the 3 valve engines.
