Here's a few pics before the teardown.
Disconnecting everything to drop is fairly straightforward. It's the same hoses, wires, etc. that need to be disconnected to go out on top. Additionally the driveshaft has to be disconnected, transmission mount removed, T-bars separated from the LCAs. There's enough room to lower the engine with the radiator still in, but we removed it anyway as an added precaution. The steering column had to come all the way out as the #3 header would've interfered.
Greg built a dolly specific for engine pulls.
