I've rebuilt many 1992 through 1995 350 engines in Z71 and siliverados
and have yet to see a 4 bolt main. I've only seen them in the 3/4 tons and heaver.

There were 3 different 350's available as options in the 1986 Chevrolet and GMC pickups, 160hp, 165hp and 185hp. The higher hp engines would be more likely to have higher compression cylinder heads, 4bolt crankshaft mains vs standard 2 bolt, and possible a heavier crankshaft dampner.
Why do fire engines engines use electricity from the mains?
Fire engines may be hooked up to the mains when parked, to use electrical heaters to keep the engines at operating temperatures which makes them run better from the start, and to let on-board chargers keep the batteries topped up. Some may even have built-in coolers for medical supplies.

How do you tell either four bolt or to bolt main on gm engine 1024388 without removing the oil pan?
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.
