What motor does a 1989 z71 have?

The 1989 Chevrolet Silverado Z71 (the Z71 was an off-road package, not a separate model) could have come with several different engines. The most common were:

* 5.0L (305 cubic inch) V8: This was a popular choice.

* 5.7L (350 cubic inch) V8: Also a very common engine option.

* 6.2L (377 cubic inch) V8: Less common than the 5.0L and 5.7L, but still a possibility.

To know for sure which engine *your* specific 1989 Silverado Z71 has, you need to check the vehicle identification number (VIN) or look for the engine's displacement stamped on the engine block itself.
