    You dont have to swap a reluctor wheel as long as you have a matching computer. You dont need to change the motor mounts just get motor mount adapter plates. And depending on which trans you plan to use you might need to change flexplates. Also depending on which trans you use you might not need to have a different driveshaft. Youll need gauge sending unit adapters to make your gauges work.

    i swapped a 08 5.3 into a 94 chevy. just scroll through the thread and you'll see EVERYTHING you have to do to make it work.
    if he is getting the LS2 torn apart just change the reluctor wheel while its apart. just look at my thread you'll see all the info you'll need on a Gen IV block in a Gen III truck set up.

    good luck.
