Default 1997 4x4 Blazer LT VIN "W" 4.3 Vortec Engine Removal/Installation

I don't think I can solve my engine problem (Thread-97 Blazer valve adjustment). I have a pretty good deal on a replacement engine and I don't want to miss out. I have from July 1st to the 4th to pull a 4.3 Vortec from a 1997 Bravada. Anybody want to help guide me through the engine removal process ?

Basically you have the 2 fuel lines and 1 evap line to disconnect or cut, 2 radiator hoses, 2 heater core hoses to remove or cut, wiring harness to remove or just unplug from the engine, Starter and wiring, 3 torque converter bolts and i believe 8 bell housing bolts, 6 motor mount bolts.
I would remove the hood and radiator to make it easier.
If you want alot more room just remove everything from the front of the engine like the alternator bracket a/c compressor/power steering bracket (you might need a special puller to get the power steering pulley off) and the water pump.

Ok I need to hot wire this Bravada at the salvage yard. But this guy said "To hard to explain but you can put a flat head screwdriver and touch the two bolts on the starter soleonoid and it will turn over" ...is that true ? If not, how can I start it without the key ? Or how can I hot wire it ?

You can't hotwire it to start and run. Security system is pretty good. Need the key.

Ok. When I turn the engine over by hand turning the alternator clockwise and pulling up on the tension pulley, it's a little harder than turning my engine over the same way. Is that a sign of good compression ?

The​ oil is good, from the dipstick, going to drain it tomorrow. The mileage is 96k. The engine turns over by hand. So far so good ?

Ok I found a 98 or 99 model with the key in the cylinder, is the ignition key cylinder from that compatible with the 97 cylinder ?

As a must do or just in case ? I'm taking everything attached to the engine, according to their engine package.
