Dual snorkel air cleaners were used on the some later L78 Novas. The latest car I have that I can document the open element on is feb/70. I have a 1st week of july car but it did not come with an air cleaner. The buy it now price of $2600 is more than I paid for my first L78 car in 1974. Wow! How things have changed!!
