The carb is a Edelbrock this being a non performance application i figured it would be sufficient. The guys at the muffler shop installed 2 3inch pipes and Flowmasters from the headers to the back of the tires and no sensors on it. I'll check the fuel dump into the carband get back with yall. I really cant say it was runnin great before cause I dont hav hardly any run time on the engine it was open header so I didnt drive it much at all.
