I just got a 2000 ss camaro roller and im teing to piece together parts for a 5.3/th400 plower plant. What all years has the oil pan i can use for the swap and what mods are needed if any to the stock 5.3 harness other than the injector adapters? I know water pump has to be swapped out but what about all the other accessories and what not. Thanks for your input and help, and i amlooking for an oil pan setup, a th400 cross member for fbody, and i guess any parts that may need to be changed.
