You could test by checking the oil level with the car pulled in and again with the car backed in.
Regardless, if 10 quarts just barely touches the dipstick and does not make it into the cross-hatched area, I understand your concern. However, you can be sure that your oil pan/crankcase is essentially identical to mine. There is not enough difference in manufacturing tolerances to give your oil pan a significantly greater capacity than other LT1 engines.
Now, if you only need to add a few ounces of oil to get the level into the cross-hatch area, that is probably not a big deal. If you’re adding a quart or so, that would be concerning to me.
Here is the level on my dipstick with 10 quarts of oil and the car backed into the garage. Tough to see since the oil was just changed, but it is just below center of the cross-hatched area.

I probably added maybe a little less than half a quart after the initial 10qt fill. That slightly less than half a quart extra brought the oil level slightly under half way mark on my dipstick reading. I'm good with that.......
