Here you can see the difference between a Pontiac Style top and a Chevy Air Horn. I like the side exit Chevy Air Horn because you can put a big filter in them. Not only that but with the correct Inverted Flair Fuel Fitting you can do away with extra brass adapters and fuel fires. Seems like a good idea. I had to sacrifice a near new leather jacket once to save my 69 Firebird.
