There's only one size 5.4. It's 330CI
99 F-150 5.4 should have a 9.75 rear and an 8.8 up front. 4R70W transmission.
I cant tell you what gears are in it. Most likely 3.55s

If it still has the door sticker numbers,
someone on here can tell you for sure.
Post them.

contact a ford dealer and give them the vin number and they can tell you what it was built with.
