can it be done... how hard, just replacing wiring and ecm tuning or more... motor mounts?

 

The biggest hurdle in my opinion is trying to get the gages working right. Putting the motor physically in isn't a problem. Using a matching PCM isn't a problem but the PCM to car interface will be. Not that it can't be done but it's time consuming.

 

current performance reworks your Lt1 harness to enable the use of an Ls1 pcm and still drive the Lt1 cluster. www.currentperformance.com
