Some motor designs can trap air in the water jackets when the cooling system is drained and refilled. Usually there are bleed bolts in these situations to get the air out or it is recommended to run the engine a short time and then recheck the coolant level. I haven't checked yet, but it is possible that the 426 engine doesn't have this issue.
