hvacr,
liftin an engine (any engine) can be pretty easy...and if carfull not much to disconnect, if your only going a couple of inches. radiator has to come out, if your working on the front cover. fuel line saftey please. probaly leave the electrical connected with the battery unhooked, (safety again Please.
the front nut ....well that can be a real pain. 1 13/16 socket and a 3/4 drive/breaker bar will be a good start. it is a normal nut, (unscrew ccw) and very tight.
Hows it coming along ? get your bearings done?
