Taking the Caddy engine out

This will not be a comprehensive detailed step-by step account. You will need to posses some mechanical ability at this point. If not, maybe you should reconsider the whole engine swap project!

To begin;
Remove the hood, you'll need the room when it comes time to lift that massive engine/transmission combination. Yes, you can remove the engine and trans and still be able to roll the car out of the shop on it's wheels.
Remove the strut brace.
Remove the battery, remembering to put up the windows first if needed.
Drain the antifreeze and remove the cooling fans & rad.

Remove the air cleaner assembly and plug the throttle body with rags to keep out what you don't want to find in the cylinders when you first turn the key to fire it up the next time.
Remove the exhaust cross-over pipe that runs from the front manifold to the rear. This will give you much needed room to access the transmission linkage and electrical connections, which you can do next.
Next remove the alternator. Now the power steering pump and belt tensioner gets unbolted. Remove the lines at the pump.

 

Those power steering lines will need to be detached from the engine block later when you lift it up.
Remove the throttle cable from the throttle body.
Remove the cruise control servo. You need to do this for clearance when lifting the engine.
Don't bother trying to remove the fuel injection harness now, just locate the multi-plug on the firewall located behind the cruise control servo. Their is a bolt in the middle of the coupled plugs that you can undo. The harness can be remove easier after the engine is out. The vacuum hoses to the evaporative canister at the left headlight can be removed next.
The ignition wire connection at the distributor cap can be removed. 
When the engine is lifted up, you can decide to remove the hose clamps on the heater hose connections behind the engine, or do as I did, just cut them.

Now it's time to get that big beast up on stands.
Remove the front wheels, and remove the 2 bolts that attach the shock struts to the spindles.
Get a curved pry bar under the CV where it enters the trans. Give it a quick "pop" to remove the axle shafts. The one on the driver's side is a real bear. I got a better angle when I lifted the engine up a bit.
Remove the A/C compressor bolts to the engine block & move it out of the way.
Remove the engine & transmission mounting bolts, 2 front, 2 rear.
Remove the 2 bolts from the exhaust manifold at the back of the engine.
Now with an engine hoist, carefully lift the engine & trans together. Slowly checking that all clears. Now is the time to remove that driver side CV axle shaft & the power steering hoses from the block.
Make sure the CV axles are clear of the trans and don't get wedged between the trans and the body.

One last check to see that all is good, and....

Now remove the plastic starter cover and starter.
Remove the 3 torque converter bolts, and then the 6 bolts that connect the engine & trans together.
