upper plenum question

has any one tried to use a 75mm upper plenum for a mustang on an f150 4.6 2v and if so were there any mods to be done.

Go to your local book store or www.cartechbooks.com and get 'Building 4.6/5.4L FORD HORSEPOWER ON THE DYNO' . They have done dyno test on that swap and any other you could think of. It covers truck and cars.
