cleaner air package

I had an unmolested 67 318-2 Coronet back in the 80's and my research from FSM came up with- PCV only.

That particular engine burned so clean it actually produced a fair amount of clean water out the tail pipe.

It averaged 17-18 MPG and got north of 22 on the highway.

1968 street hemi`s came out w/ a pcv on the drivers side, and the pass side routed to the air cleaner. Also had heat tubes to the back of the intake, nothing else.
