Clean is good...
Ok, talk is everywhere but serious feedback is requested here. Some who've had cams installed kept their current gas mileage, some even improved. I recently heard someone actually lost 9 MPG with his cam install! The question is, how far can one go with a cam and not get killed at the pump? A reasonable tradeoff is good sense. I'm looking specifically at an LS2 in my 2005 with boltons to this point. Thanks for your expertise.
