Where is the Location of camshaft sensor on 4.3 liter engine?

It is located in the same place as a 350ci Chevrolet engine. The 4.3, also known as the "Three-Quarter Three-Fifty" (because it is just a 350ci block with 2 cylinders shaved off), generally has it's cam sensor underneath the driver's side exhaust manifold. Depending on the year, you may find a knock sensor there instead, and the cam sensor will be between your firewall and engine block.

Not sure what year 4.3 you have but if it has a distributor, that would be the cam sensor.
