That is way to vague of a question to answer as there are so many extreme factors that come into play.
Driving habits, climate, maintained, ect.
I've seen them hatch as early as 80k when abused and over 300k when driven well and maintained often.
They are an outstanding and reliable engine. They have problems with the plastic intake gaskets and the heater coolant fitting in the intake around 80k-120k . if you don't severely cook the engine and after replacing them they will go a long ways again with maintenance.

With proper maintanence, the 4.3l vortec motors in the '94 and up S/T series trucks/suvs (S-10/Blazer/Sonoma/Jimmy/Envoy/Bravada) should be capable of well over 200k miles before needing any major internal engine repair. The main weak points on older, high-mileage 4.3l motors tend to be the fuel pump failures, and oil leaks from the oil cooler lines and the rear main seal.
