Learning as I go, I had another question - the NHRA rulebook states that an air cleaner, if used, must be OEM automotive or retain OEM configuration. Big-block Chevy Super Sport's came from the factory with an open-element air cleaner. Does this mean I can use one of these on another GM product in Stock Class, or am I stuck with the OEM air cleaner that came on the car? And what about a K&N, which has the OEM configuration? Thanks again for your suggestions!
