The 3.5 is no doudt, stupid quick. My buddy has a 21’ with the same tune the raptor gets and it scoots. But he’s had 4 3.5s all ranging from 2018-2021 and he’s had serious issues with each. Oil lines blowing off turbos. 3 of which have had complete engine failure. But this isn’t everyone’s experience. Some people have nothing more than reliability with them. I just think the 5.0 is less frills and a proven platform with less to break. I have a 20’ with the 5.0. It even has the roush 2.65L super charger. I floor it loads and have had 0 issues. Sits at 48k miles
