good score for that price
the 3310-2 is a 750cfm vac secondary.
i'd ditch the shaker, they're for xy's and ram air mustangs, especially on a genuine xa gt bonnet that already has the scoops.
the csa's will be after market, ford never made 15x8.
you do relise this thread is hopeless without pictures
congrats on your purchase.......and welcome to the club
