As the title says do I need to get a wheel alignment after pulling the engine out the bottom??

 

In my experience, no.

 

If you detach the lower control arms from the k-member you will need to do the alignment. If you remove the suspension as part of the k-member by removing the spring/shock top mounts, you won't have to do the alignment.

My experience has been that dropping the engine in the garage, while doable, is the not the easiest one man job and less mass is easier, so i detach the suspension. If you mark the front and rear bolts on the lower control arm, you alignment will be close when you reinstall but you will need an alignment.
