So since I've drilled out my secondary baffles, my mileage has been cut in half and it smells like I'm running a pretty rich mixture now, I might as we'll be driving my 76 el camino w/ the 350. Anyways I would greatly appreciate any advice or ideas anyone has on which air filter and/or tuners I need to look at to get some of my mpg back. thankyou
