Unhappy 360 (At idle)

Idle sounds high, but my ears don't do well on videos. There should be a hose routing decal under the hood. There should also be a decal showing the engine timing. A 1979 only factory truck service manual should also have it. This is a one year only engine/emissions set up.

The sound of the video is a bit misleading, but the idle is approx. 750 RPM in Neutral and 650 RPM in gear, there is a timing label under the hood that says 10 degrees +- 2 degrees at 750 RPM.
The hose routing sticker is there as well but outdated as most of the emissions stuff is gone, our domestic emissions regulations are quite liberal for vintage cars, not so for current vehicles.
