well from where i am with it, it doesnt seem to be that big of a deal. as long as you have the eng/trans/ecm/wiring harness out of the donor car, you will need to send the ecm to be reprogrammed to work with the truck(about $600), different headers, motor and trans mount adapters, and a lot of patience.
