It’s critical to have enough fuel volume and a q-jet on a 454 SS motor would really stress your fuel system. A good pump like a Magnafuel, a #10 line from the cell to the regulator, appropriate return line, and a # 8 line from the regulator to the carb would ne required. Even if it’s a Holley I would do the same thing.

Have that setup!! Thanks!
