Generally, you can't. GM installed both 2 and 4 bolt main caps on many different cylinder block castings. Now, some blocks were never offered with 4 bolt mains. Any low performance displacement (262,267, 305, 307, etc) always had 2 bolt mains. Small journal engines (pre-1969 chevy small blocks) typically had 2 bolt mains even on performance engines.
You can replace all of them BUT the 2 in the rear of the engine block with out pulling the engine. To remove the rear ones you can either pull the transmission are remove the engine your choice.
yes when the engine is out and upside down
no.
Yes, the engine will pull right out without removing the trans.
In some cars, you can get the rear bearing by dropping the transmission. For the rest, no.

It's almost impossible without removing the engine, unfortunately.
yes, it is very simple. even a child can do it. If you don't know how to do it ask MORCHED He is famous for changing things without removing stuff.
