What is the stock torque rateing for a 1968 camaro 327?

The stock torque rating for a 1968 Camaro 327 depends heavily on the specific 327 cubic inch engine option chosen. Chevrolet offered several variations of the 327 in 1968, each with different horsepower and torque outputs. There wasn't a single "327" engine.

To find the torque rating, you need to know the specific engine code (found on a casting number on the engine block) or at least the advertised horsepower rating. Then, you can consult a 1968 Chevrolet Camaro parts catalog or a reliable automotive resource like a Chilton's or Haynes manual for that specific engine code. These resources will list the factory torque specifications.
