What amount of vac do you think I should be able to get with a stock rebuilt 292. I was reading that with my power brake conversion (dual diaphram) that it requires around 20 inches of vac to operate. Single diaphram take less! If this is true it might explain why I have never felt like the power upgrade did me much good. Still have to stand on the pedal for any quick stop.
