What did this air cleaner come on?

[John]

I picked up a single snorkle air cleaner
with the large 16-7/8" diameter lid ( chrome ) and it has
( 2 ) vents on the bottom and was designed for "positive ventlation" ...see decal
Any idea what it came on? 327, 396, or 427 ?
( It is possible that the lid came off something else )

I believe that is a 67 Camaro Chevelle Nova Impala small block air cleaner with California emissions A.I.R. I had one on a 67 327 Camaro that came out of California.

I was thinking that it is 67 with emissions as well... I just read the thread today on the CRG board about smog and the 67's had 2 inlet pipes on the A/C base... one appears to be hooked to the draft pipe typical on 67 back small blocks and the other was the draw for filtered air to feed the smog pump.
