The car I just purchased has a healthy 454 and I think the previous owner was going to make it more drag than street. My intention is all street. He installed valve cover breathers with hoses running down the inner fenders like he was going to hook them to the headers for evacuation but never did. Am I better off just putting some regular breathers on the car or put a oil fill cap on one side and install a PCV valve on the other side? Should it be hooked to the carb if I do or directly to the intake?
