I have stated before that Reichard Racing will make 2 adapter plates and you can use either a bullet or regular p.i intake from a mustang gt. Either of these intakes can flow a good amount of air and will help the 5.4 benefit from a good set of ported heads and a cam set up for towing/hauling. I wouldnt want more duration at all because that would steal low end torque, I woud go with a bit more lift and mabe a 116 lsa.
