According to the manu they say dont go this thick for a disclaimer.
However, we have guys that recently ran oils in the 15 viscoity range in the 5.7 with nothing but great news with hemi tick, ask hemi395. Even with draining 2 quarts with your oil your viscosity would be somewhere around 13 after you put 2 quarts back 5w40 redline. Best news you are in florida, very unlikely to have any issues going thicker.
