My 440 installed itself lol, when I was swapping in my 440 I had it sitting on the mounts, 727 was in it with a jack under it and raised up to the tunnel.
The engine was on the cherry picker and every frigging thing was a 1/4" off, locate studs for the bell, mounts on the engine lacked just a bit from sliding over , I was by myself , pry bar , beer , ect cussing. Lol.
Said F it and went in the house for dinner, came out after and that thing had slipped into place,
Sitting on the mounts, bell was on the block.
Picker must have leaked down a bit I don't know , funny as he// , glad my fingers were not in the way.
