Yes its a 4 speed. I can't give you a honest answer to that because I have a Lakewood bellhousing and the Z bar had already been altered before I bought the car. It was altered so the Hooker headers would fit I assume. I did however had to grind off a 1/4" of the bottom of the Z bar in order for it to clear the header when the clutch is pushed in. I assume it will be the same way with stock four speed and bell but I could be wrong.
