72 mustang; Erson Cam Vacuum readings.

A short video of the vacuum readings on my 72 mach 1's 4V 351c. I could only get 5-6 inHg at idle. The Erson cam is unknown what it actually is but has a very lobey idle. On top of that It's running a Edlebrock Torker single plane intake. Vacuum readings are the same with all other lines are capped off as well.
