Will a 4.3 z engine from 1992 s10 blazer fit in 2000 blazer?

No, the 4.3 L Z engine from a 1992 S10 Blazer will not fit in a 2000 Blazer. The 1992 S10 Blazer uses the first generation of the 4.3 L Z engine, while the 2000 Blazer uses the second generation. The two engines are not compatible and cannot be swapped without significant modifications.

Here are some of the key differences between the first and second generation 4.3 L Z engines:

* The first generation engine uses a distributor, while the second generation engine uses coil-on-plug ignition.

* The first generation engine has a different cylinder head design than the second generation engine.

* The first generation engine uses a different intake manifold than the second generation engine.

* The first generation engine uses a different fuel injection system than the second generation engine.

These are just some of the key differences between the two engines. There are also many other smaller differences that would make it impossible to swap the engines without significant modifications.

Therefore, it is not possible to fit a 4.3 L Z engine from a 1992 S10 Blazer into a 2000 Blazer without significant modifications.
