they are bullit proof!
Yes, but why? Its a big job and requires re wiring for engine computer etc The 3.8 GM engine is a more reliable and smooth running engine than the 3.1 GM And the 3.8 generally gets better fuel economy when comparing the cars equally.
In GM trucks or new GM cars, the 8th digit of the VIN # is the Engine.

The 3800 II is the battle axe of the 90s to 00s lineup. The engine is not as much well constructed as it is strongly constructed. The engine is fairly reliable, its no Honda D/B series but as far as a GM engine it is one of the more reliable engines they have made. Also considering how many models used the 3800 II, replacement parts are cheap and common.
The 302 CUID engine is a Ford engine, not a GM engine.
Yeees?
A complete GM Ecotec engine will weigh about 300 pounds. This of course is the complete engine, down to the bolts and all.
Very reliable except for the fuel pump, GM's down fall.
