Your lower hose attachment appears to be much lower than mine at the radiator.
On my 75 Dart Sport with BeCool aluminum radiator and a big block with left side water pump inlet the hose would barely touch the strut rod when the front end was raised but would barely clear it at normal ride height. My lower hose is a little more above the strut rod and would get touched from underneath. Current engine in picture will be a small block 360, but lower hose is in the same spot for reference.
