At 7 quarts, your sump is already oversized compared to most cars. An oversized sump will not cause a reduction in oil loss. You may however, wish to check your CCV for proper operation, and check for engine oil leaks. One of them should be the cause of your oil loss. Some 330's just seem to burn oil in spite of having none of the aforementioned problems. My theory is it is because the 330 is a stroker motor. ( a stroked 325) although some may disagree with this. I have owned several strokers, and all burned more oil than before they were stroked.
