Question concerning California emissions laws

[histoy]

Does anyone know in what year California mandated that dual snorkle air cleaners were required for our 440 engines?   I've been told both 1967 and 1969, so I'm not sure which year is correct.  Also, would it make a difference whether the 440 was equpped with air conditioning?

i believe it was 1969 in CA - then followed by 1970 for all other states...   this is just an educated guess from what i've seen...   do not take it as gosple

I believe that in 1967 the dual snorkel was the only air cleaner available for the 440 high performance and the California mandated one appeared in 1969.  So both answers would be somewhat correct.

last I heard 74 and older are exempt

unless you're doing an exact resto you can choose whichever you like

It wasn't the number of snorkels that were mandated, it was the heated air cleaner which arrived in '70. Only one snorkel heated by the exhaust manifold heat stove.

So, if I had a California '68 R/T 440 AC car, would it have an unsilenced air cleaner or a dual snorkle one when it left the factory?

i believe unsilenced
