My engine needs replaced in my vehicle listed above. I have an opportunity to buy a LT1 complete engine and transmission with computer and all for cheap. Can it work in the Trailblazer?

Good afternoon,

It will be a big project but yes.

You will need the complete engine harness, exhaust system, driveshaft, cross member and all accessories mountings brackets.

Then the harness needs to be adapted to your car's dashboard.

Like I said, big project.

The transmission you are getting from the donor has to have the transfer case with it.
