Ok, so who really needs 'more' out of this truck? It's already faster than most on street, including some hi priced sports cars. I get you want the sound, so either sell your raptor, or make a recording and integrate into the audio system.
Wait, Ford already has it! It's in the Mustang!
This setup is ideal with the trans setup to keep in power band. and with a tune, you won't need to think about another motor. I bet most of the people talking about getting the V8 have never experienced the Gen 2 in dirt.. it's absolutely perfect. more torque/HP avail quick and with less effort than most V8's now.
Stock is dog slow
the statement "who really needs more"? is an ignorant question.
