James,
Thanks for letting me know about the ELC Code=BB=Cowl Plenum Air Cleaner. It apperently was never installed when this car was new because the original owner, a friend of mine, never ran the car with the CPAC.
Brooks did have a 1969 White COPO. He was a big drag racer and supplied a lot of the HP cars in our area.
He also ordered a Capri Cream, 67 SS Camaro 396/375, with radio heater delete and 456 read end as well as a Butternut Yellow Z28 with radio heater delete and 4:88 rear end, which is the car I now have. His plan was, which ever car sold first, the other would be the Brooks Chevrolet Super Stock race care for that year. Attached is a photo taken from Mr. Brooks office showing the 396/375 SS Camaro sitting in front of the Dealership after it was lettered up. You can see the Window Sticker still on the quarter glass.
Houston Platt, Georgia Hall of Fame Drag Racer, drove this car that year, “Dixie Twister, Jr”
