Pentastar motor

What about swapping the whole wiring harness, ecm/pcm, cluster, blah blah blah into an A-Body. Basically the whole newer vehicle, inside the shell of an A-Body. If you could get the whole works out of a junk/wrecked car, I mean.

And then you could always hide the stuff your not using (like the cluster) and use one of the Splitter style speed sensors (like the ones found in the late 80's/early 90's trucks) to run both the newer cluster (hidden) and the original cable driven cluster/
