Prop clearence

Thoughts, opinions or measurements requested. RV9 rebuild project is coming along. Today some of the big pieces are bolted up. Fuselage is on the gear with the stock wheels and tires on. IO 320 and Hartzell HC-C2YL-1BF/F7673-4 blades installed. Prop is 72? diameter. With the prop vertical I have a little over 7.5? of clearence from the floor. Doesn?t look like a lot considering the weight of the rest of the plane not installed yet and when installed will compress the gear to some degree. Digital level on the slider tracks shows 2.5 degrees nose down(tail is in a fixture for now). Just wondering with plane complete with paint, fuel, crew ect ect how much prop clearence there might be in a wheel landing attitude? Throw in a firm arrival. Will the gear flex 3-4 inches?

Prop clearance will not change appreciably when the aircraft is complete. The vast majority of weight is on the mains. When repacking the bearings on my 6A, the nose just came straight up with virtually no deflection. You will see deflection on the mains when jacking a complete aircraft.
