Z-ing the front frame w/ Engine still in

I need to Z the front end of my Armada to raise the suspension and wondered if anyone has done this with the engine still in? If anyone suggests it would be easier to pull the motor please suggest that too...just trying not to make this project and more difficult that it already is.

Thanks.Aaronwww.artofnoize.com

i Z'd both my toyotas with the motors still in...was pretty easy..but not sure how that would compare to what your working with

It sucked my ass on my suburban with the engine still in ...pull it if you can .....just my 2 cents

ive done several with the engine in, only thing that makes it harder is having to work underneath to weld up the insides of the frame....
