Apparently in '48 (prior to production of the '49s) Ned Nickles ?BMD stylist? drilled holes in the fenders of his '48 Roadmaster, installed amber bulbs & wired them to the distributor. When the engine ran, they blinked on & off in sequence. Ed Ragsdale saw them and declared '3 holes for the Super, 4 holes for the Roadmaster!' and the rest is history- tho without the light bulbs! 8(<P>Of course the official name is Ventiports. <P>The early '49 cars had hoses hooked up to them to help vent engine heat, but by mid-year the Ventiports were sealed off. Years ago as a teenager, I remember seeing a '49 in the junkyard with rotting cloth & wire ducting hoses hanging down on the insides of the fenders and my mind reeled trying to imagine what the hell they could be for. If I had a 'portholed' Buick, I would light 'em! Ironic for me, being I dearly love the Ventiports, that I chose one of only 2 years that doesn't have 'em ('59).
