Brandon,
Chevrolet has never been positive ground...they have always been negative ground. You might be thinking of early GMC trucks which were positive ground.
A big red cable goes to the starter solenoid and a big black cable attaches to the engine block or a mounting bolt on the starter.
The positive post on the battery is a larger (top post style) diameter than the negative post. Both post are usually marked with a + and a -.
If Chevrolet ever did produce a positive ground vehicle, it was when Moses was a small boy! Good luck!
