Here is how I remember removing the LT1/T56 from my z28. Going by memory, sorry no photos. Please feel free to add your comments/tips/warnings and I will update this post. Hopefully this quick write up will help someone out...

Step1: top of the car, engine bay
Remove hood struts, hinge bolts, hood
Disconnect battery, remove
Remove air box, air filter
Remove front accessories (alternator, a/c compressor, p/s pump) fromm block and set to the side
Drain antifreeze and remove radiator
Disconnect all wiring to sensors, grounds, etc (label everything)
Support engine with hoist from above
Make sure all hoses, wires etc will clear engine coming from top

Step 2: Inside the car:
Remove shifter ball
Remove center console to access shifter assembly
Remove 2 bolts to shorten shifter (for clearance issues)

Step 3: Under the car
Lift car, place jacks under front K member on each side where control arms are.
Remove rear X member (4 bolts)
Remove transmission mount to X member
Remove all wiring to transmission
Drain transmission
Remove transmission arm from transmission to rear differential
Remove 4 bolts (2 each time) holding output center shaft universal joints
Remove output shaft by taking off rear u-joint first then sliding it off transmission
Catch any transmission fluid that may leak

Step 4: Under the car
Drain engine oil
Drain antifreeze
Remove starter
Remove clutch slave cylinder
Push fork down to disconnect it from throw out bearing
Place jack under transmission
Remove 8 x 15mm bellhousing to transmission bolts
Separate transmission from bellhousing by moving up to clear shifter handle and transmission shaft. Lay transmission backon floor out of the way

Step 5: Under the car
Support engine from below using jack
Remove 2 block mount super long bolts (need tool on head bolt and one on nut)
Remove downpipe coming from driver side By removing 3 bolts (13mm) right above catalytic converter

Step 6: Both above and below car:
Start lifting engine while using both jack and hoist from above
Make sure no wires are catching to block and that block is free to come
Will need to rotate front of block slightly toward driver side to clear driver block mount
Once engine is off car, lay down on ground using wooden blocks
