does anybody know if u can swith just your 4.6 block to a 5.4 block and if u can what do u need to do it or is there any websites that has info on it

Block? The difference between them is that the 5.4 has a longer stroke than the 4.6, because of this, the 5.4 has a taller deck height.

You'll need a different crank, I'm not sure on the rods, they may be the same. The pistons will be the same because it has the same bore.

You're not going to pick up as much power as you could hope, the biggest restriction is the heads. 2v heads just don't flow enough for even the 4.6, they are just as bad for the 5.4.

Otherwise, all your other things will transfer right over, you'll need a 5.4 intake manifold, OR you can use your 4.6 intake manifold with a couple of spacers.

thanks dude but i meant a short block ,will my supercharger bolt up its centrifugal and why dont u hear about people doing this

ShadowDrake

Yes it will bolt up. I don't know why more people don't consider the 5.4. It's not much more than a 4.6 when you're paying for a built short block for either variant. It's a modular motor so it's 99% the same. You may need to modify some of your blower tubing because the dimensions won't be identical between the two blocks... it'll be close though.

someone makes an adapter that allows you to use your 4.6 intake manifold so it will fit under the hood.
