The parts house sold me an oil filter that was supposed to be for a 6.7 in a Bluebird school bus but it is to small. My nephew the Diesel guy told me it should take 3 gallons to change the oil in a 6.7 and it took 5 gallons due tot he large filter size. So I am wondering if I have the 8.3. What is the quickest way to tell?

Send us some pictures or locate the engine data plate/sticker. Some Scan tools will display which engine it is, tho not everyone has access to this on a whim.
If the engine serial number is displayed on a data plate inside the bus, you can also go to the Cummins Quickserve website, make a free account, and punch in that serial number to get all the Cummins service information whenever you like.
IIRC, the 8.3 has a much larger front cover than the 6.7
