Removing  Pcm
The engine wiring harness is best left in place when removing the LT1. First step was freeing the PCM from its slot under the cowl, and disconnecting the wiring harness from that of the car's interior. There is a group of wires and a grommet on the passenger-side firewall that leads into the cabin; once you remove the kicker panel in the interior it's easy to unplug and push the wires through the hole.

Disconnecting The Power Steering Lines
In addition to the wiring harness, the power steering lines and the front brake lines must also be disconnected in order to drop the motor and front subframe. All other hoses, such as those that run from the water pump to the radiator, fuel lines, and transmission fluid lines must also be unhooked. Don't forget the steering shaft bolt!

Unbolting The Transmission
With two furniture dollies (bought from Home Depot) under the front subframe and transmission for support, Chris removes the bolts on the trans crossmember, then the strut tower bolts, and finally those that connect the K-member to the frame.

Front Control Arms Tied Down
It's important to tie up the front control arms as seen here, otherwise your front rotors will scrape on the ground as you maneuver the engine and cradle (not to mention that the brake lines will have undue tension on them).

Pulling Engine Up
Slowly, the body is raised off of the front subframe and motor, as we check periodically to make sure nothing is being hung-up. Though we had initially hoped to remove the motor with the alternator/power steering pump/A/C bracket intact, that appears impossible on the LT1. Werner referred to it as the "automotive equivalent to a chastity belt"--and deservingly so. The alternator needs to come off, but the bracket, power steering, and A/C stay with the car. And let me tell you, messing with this non-sensical contraption is no fun. Make sure you label your bolts as you remove them, as it will prove crucial later on.

Lt1 Engine Removed
After hours of cursing, here she be! We were careful to clean up the mess afterwards as we didn't want an ecological disaster on our hands, nor did we want Werner's pack of dogs lapping up these harmful fluids.
