I HAVE A 93 GT WITH A 302. MILD BUILT. RUNNING A 750 HOLLEY QUICK FUEL CARB. HOLLEY BLACK FUEL PUMP. LOOKING FOR A GOOD TIMING SET UP AND FUEL PRESSURE ADJUSTMENT... THANKS
With the limited info I would say set the fuel pressure at 7lbs and the timing at 12°, that should get you started, you can bump up the timing to what the engine likes as you drive it. You will also find if the fuel pressure is ok, if it runs out at the top end you can bump that up a couple pounds at a time.
