Auto carby has no overrun enrichment system, and has additional vacuum solenoids for idle-up. The jetting is the same auto/manual though.

so i need to use the manual carby?

its for the auto.. they only have 2 gears
The overrun enrichment system is for manual carbies, and it works when the engine is in overrun - basically when you back off the throttle in any gear and the motor is being driven by the wheels instead of the other way around.

oww i thought u said over drive haha
From my experience it is problematic to use a manual carby on a motor with an auto box. I would swap the jets from your F8B carby into the F5A one.
You're also going to run into issues if you only have an F8B manual intake manifold too, because it is missing one of the temperature control switch for cold start idle.
