My basement is roughly 15ft x 15ft x 7ft cube = 1575 cubic feet..
SO if this is all correct then my furnace uses one full volume of the basement in combustion air every 5 and half hours..
And that doesn't count what the baro is sucking up the chimney which I would think is grossly more than combustion.

It doesn't take a lot of btu's to heat just the air, so some amount of turnover of air is not a big problem. If anything, turnover of air is needed to maintain the quality of the air in the house.
