Firing motor after a long sit!

[tex_waco_usmc]

So I built the 350 4-bolt main in the 67 about 5-6 years ago. It has never been driven but before my last deployment it was run weekly to keep it going.

Now, 2.5 years later I have pulled the fuel tank to replace with an underbed tank. Im about to get ready to try and fire it again for the first time since before I deployed.

What should I do before attempting to fire this engine that has sat for so long? It does turn over easily nothing is frozen... Im looking more along the lines of the carb, oil, etc...
