I tried to buy one of the new 4500 arrow intakes you pictured 1st and was told they only cast enuff for the drag pack motors they built, and Mopar had the castings and at the time wouldn't let arrow buy them. Also if I remember correctly that intake wouldn't work for a regular gen3 head, supposed to be specific to those heads which are also specific to the drag Pak motor only. Don't know what all is different in the head but something with a moved port, different rocker system for lash cap style adjustment like a NASCAR motor.... I should call again tho cause I too wanted an as cast dominator intake but had to settle for the adapter version they sold.
