I've heard that the JK with auto trans is one of (if not the) most parasitic drive trains out there. The only trucks that I've seen making 400hp at the wheels are not naturally aspirated. Before making the swap I spoke with Arrington Performance and Southern Hot Rod who both can get you to 400hp at the wheels with some limited warranty. My craziness ends at whatever the 392 can produce at the wheels.
