Sorry my bad. Unknown from my seat. 4.4 is significanlty bigger wrt mass so by default it should handle more abuse.....how much more I cannot say. Make sure the repair shop does the proper pressure tests if they replace any coolant parts. If the engine is warm and then they do the test for a good while you could tell if anything internal is blown or leaking. Dealer did a 20 minute test on a cold block for me so they missed the cracked head which showed up in a very obvious way about 2k miles later.
