There's a video on YouTube where a guy pulls a 6.8l out of a cutaway van with an engine hoist. I think he pulled the intake manifold off and rigged a lift point tight and low in the valley with a chain. At some point I think I saw a picture where someone welded up a mount that attached to the front of the engine using various bolt holes for accessory items that cantilevered off of an engine hoist arm. With some thought I bet your could pull that 5.4 out without a problem.... if you have too.
