thanks andy, pics and illustrations help me out a lot. I will go get some more tubing and re pipe it . you said the motor vac goes to the middle port but your illustration shows it going to the top and the middle going to the vac doors.. may be a couple of days before I get a chance to redo it but I will report results.
what book is your diagram from?
also no cam stock motor
