Trailblazer I-6 to 5.3 swap???
 

what would it take to do this? im sure computer and harness would have to be swapped as well as some motor mount work, but would the trans/t-case bolt up? what about the rest of the electrical? could the bcm and other onboard computers be flashed to accept the 5.3? just thinkin about some options for my wifes trailblazer thanks!
