relatively easy to do, the motor should bolt up to the trans adaptor you have, the flywheel might need to be from a comaro, or it might even use the one from the v8 thats in the car currently. as for the wiring as long as you get the motor with the ecu harness and ecu you can have the ecu reprogrammed to run in your car, it wil require certain things to be disabled like the "pats" system and mabye and oxygen sensor or two. there is a company called hp tuners that specializes in doing this stuff and they can walk you through the steps even to adapt the wiring for your application via their forums
