I've done it both with the trans attached and with the engine alone. If you have the trans attached already, do it that way, but here's a couple basics: first, you need to get the car up off the ground a bit, and you need to get a hoist capable of getting the engine and trans high enough to clear the radiator support with the car off the ground. I prefer to use an engine tilter (I don't know the official name) which attaches to the front and rear of the motor in 4 places and has a crank handle on the front to allow you to tilt the motor enough to get it all in there at once. You can sometimes rent or borrow these tools, but I have one I bought at Harbor Freight for something like $29 and it works fine. I'd also leave the crank pulley off until you get the motor in as well. My usual motor install drill is to have the front wheels on my ramps, the rear of the car on axle stands and a friend underneath guiding the trans. You likely need another buddy to work the cherry picker and you can then guide the motor into place.Everyone needs to work together and work slowly and carefully to avoid dropping the motor, tipping over the cherry picker, or worse getting someone hurt or killed. It's very simple, but not the kind of work you want to get in a hurry while doing.
