This is my first time priming a motor so please bare with me. I finally have the time to install my newly rebuilt cam sensor, my car has been sitting in a non-heated garage since Nov.2013, so I thought it would be a good idea to prime the motor before the installation. What is the proper procedure ? Do I just install the priming tool and turn it using a drill until I see good oil pressure, then install/set the cam sensor and fire her up or is there more to it than that ? Thanks for your help, Kyle.
 
First and most important disconnect the orange wire behind the battery, and you must have an oil pressure gauge in order to make sure you do built up oil pressure before you reconnect the orange wire for start up.

I didn't pack the oil pump with Vaseline as most do
I first filled the oil filter as much as I can and then put 3 quarts oil in oil pan , then I remove the lower oil cooler from the radiator taped it against some pipe so the oil cooler is vertical position. Then place a small funnel inside the oil cooler hose, you will need a Chevy oil pump prime tool and place it inside the Cam Sensor hole; make sure the tool slot is fitted on the oil pump shaft. DO NOT start the engine, if your oil pressure gauge is electric then just turn the key to the "ON POSITION" , and have someone inside the car telling you that you have oil pressure. Attach the cordless drill machine to prime tool and run it at CCW position, at the same time fill the oil cooler hose with about 1-1/2-2 quarts of motor oil, or until you have oil pressure present. Once you have oil pressure, re-install the oil cooler hose back, set the cordless drill machine to CW until the other person inside the car tells you that you oil pressure on the gauge. Remove prime tool rotate crank shaft to new marking of 25* after TDC install the Cam Sensor as per Casper's Instruction.

And it you don't have a Casper Cam Sensor Tool then you use this read up.

If you haven't pulled the sensor out yet, just start the car and watch the light. If you want to be extra cautious, unplug the ECM wire and watch for the oil light to go out. (the starter won't care much for that, but if it makes you feel better, why not?)

That's what I'd do, no sense going thru all that other monkey motion. If your dead set on wanting to prime it manually, just engage the priming tool in the oil pump shaft, spin your drill CLOCKWISE until you see pressure on your guage, or if you don't have a guage, you feel resistance from the drill spinning the pump shaft.
 
First I want to thank you guys again for all the help, I just finished priming the motor and installing my newly rebuilt cam sensor, car runs great ! :)
