I have always noticed the 4.6L, 5.4L, and 6.8L Triton engines have a very unique “strong” startup sound from the factory. When the starter is cranking the engine over they are louder than most other engines. Sounds tough is the best way to put it. Is it simply just the Ford starter?
Once they fire they sound just like any other V8.
