Glad you found the firing order was off. If anything will cause poor running and popping through the carb, that is it. I would get someone who knows Quadrajets go over the carb. You had dirt in the gas and I think you said you ran the car with no filter which is never a good idea. Despite what others have said the stock brass sintered filter are actually very affective at removing debris. They are small and will clog quickly if you have a lot of debris in the tank. You may want to use an inline filter after the pump rather than the stock sintered filter. I wouldn’t use both. Properly setting up the carb will be important to getting your car running really well. Also if I were you I would replace the points with a Petronix unit. It will save you a lot of aggravation, for the $80 investment they are a no brainer, especially with a GM motor with the distributor at the back of the motor.
