If you use the original dip stick the oil will be below the seam where the pan and block meet and below the crank. Our motor has the crank not swinging below the block. Since the crank can’t airate the oil if it’s below the block / oil pan line you can fill it to the normal dip stick’s reading without issue. Since the oil line is below the pan gasket there should not be a leak just from having ‘too much oil’ (pan should be sealed properly anyways).
I use the Canton 7qt on my Marauder, the only one shallow enough to not hang below my cross member, but with bigger side ballasts. Had it modified to clear the cross member and fill it as normal on the dipstick. Also have an oil filter relocation kit. Takes just shy of 9qts.
