I think they do since the fan shrouds are different, but I am pretty sure I yanked this off a small block since big blocks are rare finds at my local Pick N Pull junk yards, also I took pics of the donor truck and the engine, but my computer crashed during the last house move, so it may be a while before I recover them

the clutch fan measures 19 inches and my flex fan, which fits the radiator shroud appears to be 18 inches
