BACK IN THE OLD DAYS I had a 1966 Dodge Dart GT 273 4 barrel . Someone stole my air cleaner. I replaced it with a small paper air leaner. Sounded great when that 4 barrel opened. Well after 35,000 miles the car was using a qt of oil in 500 miles. We took the motor apart and found that the motor was actually bored out by all the dirt that the crappy air filter let in . The ring gap was .050 over size . So between the ring wear and bore wear the rings lost there spring, and allowed the oil to pass. Moral of this story clean air is better than that 1/2 HP gain. <LOL>
