4.6L to 5.4L block

Latvik · February 8th, 2012, 09:21 PM

Ok short and sweet, what from a 4.6L engine (heads of course) can be swapped onto a 5.4L block?

Was looking at prices for 5.4's in the mid $1500's with 150k+ and then saw blocks for $250 so it got me wondering.

I have PI heads from my 2002, etc.

thanks

Heads and oil pan. That's about it.

provided it's the same
2v-2v
3v-3v
4v-4v

any other combo I was told won't work/fit

Maybe someone can confirm?

Any head from a 4.6 will bolt onto a 5.4, the same goes for any head from a 5.4 will bolt to a 4.6. These motors share parts, anything that isn't specific to the height or width differences (timing cover, intake manifold, rods, etc) can go either way.
