Got a 1985/5 speed Z28 mods??

I just got this car and yes it needs some work, and yes it is my daily driver. I am putting a catback exhast on it. Other than that it is 100%stock. Any easy carb mods I could do? I am more a TPI guy. RIght now it seems to run rich

I've done the following in and around the carb: Dual Snorkel from an L69, KN filter, air valve tension tweek (see the tech articles), DR secondary metering rods with G hanger (a B hanger is in the mail).

These mods were pretty cheap considering: The dual snorkel was $30 from a yard; the KN was about the same; the a/v tension tweek was free; the B hanger was $3.00; and the DR rods were, if I recall correctly, $24. I couldn't say if the car ran rich from the factory or not.
