Fast 95 Z28

So heres the scoop. I built an LQ4 408 and its running very rich as you can see in the picture I attached. I'm wondering if anyone knows which size jets I should run? I'm not sure what jets are currently in the carb as I bought it used and just slapped it on the car. Not sure if my small air cleaner is causing the super rich condition its a 10" air cleaner. I'm only running a 10" cleaner, because thats all that fits in my shaker scoop. I'm at sea level the combo ran an 11.48 @116.64 second pass. I'm happy with the E/T just thought it would trap more MPH. Heres the specs...

Not really sure, I bought the carb used and just slapped it on the engine. I thought I would try and ask before tearing it apart. Was just wondering if anyone else have a similar combo with experience.
