40lbs of grapes in an 8 gallon fermentor?

[Inverted]

Is this going to be too much headspace for primary? I am aware this will make around 3-3.5 gallons of must and I will do a 3 gallon carboy after I press, but will I be able to ferment in my 8 gallon bucket without issue?

Yes, should be fine. Headspace is not an issue in primary
