Reviving a 360

So I'm buying a 1976 D300 with a 360 and a 4sp manual trans and the plan is to put them in my 73 Duster currently equipped with a 198 /6. This thread will mainly be my progress and any questions I have and general 360 converstion. So next Saturday I plan on getting it. The guy I am buying it from hasn't had it running, but sent me a video of it running the day before he bought it a few months ago. I am hoping to get it running before I buy it so I know for a fact it is a solid engine. The tank is missing so I will bring a gas can, battery starter fluid (obviously) anything else you guys can think of? would it be worth it to stop at an auto parts store and get some new plugs?
