Other than the code on the data plate, ( code 4 is a C-6) the C-6 has a torqe converter housing which is part of the transmission case whereas the Cruise-O-matic has a bolt on TQ housing. Also, on the C-6 equipped cars, you can see the wiring for the neutral safety switch running on top of the engine or routed along the engine and running along the back to the transmission.
