starting a engine

i bought a 42 mb project. it has an earlry 80's 229 v-6 that supposedly was "gone through". it has been sitting for at least 5 yrs that i know of. what steps should i take before trying to start it?  

First drain the oil and replace the filter and fill with new oil. I would pull all the plugs and put a squirt of auto trans fluid or Marvel mystery oil into each cylinder (don't use a lot, a couple of tablespoons will do). Let it soak over night then by hand rotate a couple of times. Put the plugs back in. Make sure the trans and transfer case have required amount of gear lube. If the fuel tank has the old gas in it drain it and put fresh gas in, if there is a filter replace that too. Make sure the radiator is filled with fresh antifreeze/water. With the coil wire off crank the engine observe oil pressure, it should rise as you crank the engine. Put the coil wire back on and start it. it will smoke a little but will clear out as it warms up.  

thank you
