A true Ram Air system from EELCO that I put on my 1968 Pontiac Bonneville, 428HO 4-speed. Patterned after the Olds W-31, "Streetsweeper". Check the inlets on either side of the nose connected to 2 giant hoses leading to the aftermarket aircleaner housing. Problem with overpressure at high speeds required drilling holes in the air cleaner housing.
