It seems that the aftermarket has taken a liking to the 5.4 motor and F-150s in general. I just read in the latest MM&FF and Superford that Holley has an intercooled "Thunder" roots blower kit for the 5.4. I believe the compressor is a B&M and they claim 390 HP / 445 ft-lbs Trq (motor figures). If this is true, this would put a 5.4 F-150 owner in the ball park of the new Lightning (which is under-rated from Ford)!!
