how to bring it back to life?

[bigun911]

Ok experts I need advice. I was given a 72 c10 that has been sitting in a garage for almost 20 years. To my knowledge it ran when when parked but hasn't been started since it was parked. My thought are to change oil and coolant, pull plugs and squirt some oil sown in the cylinders. After that turn it over by hand, prime oil system with a drill, add fresh gas, and see if it will start. Outside these steps is there anything I should do to make sure I don't injure this thing. Once I have it started I will put fresh fluid I. The trans, differential, check the brakes and see if it will drive around the block

The truck is a 350ci / th350
