I want to install a vacuum gauge on my 70 Charger 440 4-speed. The question I have is why are some gauges for Vacuum only and some have vacuum and boost. I assume the boost must be if your running a blower???? Well I am not running a blower so do I need the Vacuum/boost gauge or will the Vacuum only gauge be just fine? Thanks

You are correct.  PSI side is for boost from turbo or supercharger.  You can use a vacuum only gauge.
