Thanks for taking the time to explain .. Sounds like a good setup.. Its different to what i tried . I am about to try an auto shift with turbo/efi windsor and your setup is what i'll try .
I was given some time ago a setup with 2 oneway valves but it didn't work. I tried a few different valves of different weights and still held vac in the line . In the end i went to manual valvebodies ..
