Are you running PS, if so it can/will be more complicated, MS its a breeze, I think i was able to install the DS on one of mine with PS (it was a 440), I just lifted the DS as much as possible leaving the PS mount in place just a bit loose, this was on spool mounts, it was a bit tricky but it was easier from the top, once you sneak it passed the steering shaft & it wraps around along the block its home, IIRC, you need to almost go in a straight direction untill it gets low enough.

Just lift the DS as much as possible untill the trans hits the bell housing, but leave the PS mount in place, this way you get more of an even DS lift from the F&R of that side apposed to lifting the hole engine & it mainly just lifts the front of the engine more if you understand what i'm saying.
