total timing is set at what rpm

Im lost #-oI know how to set stock timing on engines,but I am lost on timing the modified 360 on my Duster.And non of this advancing at 30 deg at 2000 rpms is really making sense.I need to find a video on how to do this.lol

You need an adjustable timing light..to set it as i do bring the motor up to 2500 rpms set the dial on 36,shoot the timing and turn the distributor til the timing mark lines up with 0, lock the dist. and your good to go been setting my timing like this for years,on my 416 and 360 no ping hesitation or any other issues of coarse i'm running an msd system,so no vacuum advance to deal with...34 degrees may be just fine for your motor run it and find out...
