Engine swap

Asked by Sterlin Sep 01, 2019 at 08:00 PM about the 2003 Chevrolet Trailblazer LTZ 4WD

Question type: Maintenance & Repair

My engine in my 2003 trailblazer spun a bearing
and I know these came with the 5.3 engine as well
but mine has the 4.2 vortec. Could I do a engine
swap with the 5.3 for a 2003 Chevy 4x4 without
changing the computer or anything?
