Thanks Jim2, I had to read that 3 times but I understand it now :o

Hey thanks a lot guys for the insight. the thought of trying to get retard out of this dizzy on boost was giving me heartburn, now it makes perfect sense. So in theory (not going to do it) one could remove and cap both vacuum lines to the dizzy and the car would not hurt itself, assuming the dizzy advance plate was not stuck full advance. In my 87 I guess the only thing it really does in a warm car is retard ignition timing at idle for emissions, since the thermo-switch is not allowing vacuum to the advance side once the engine is warmed up.

Thanks again guys I really appreciate the help.

I remember several of Chets posts saying he disconnected the lines to his dizzy, I didn't understand why it worked better for him but I do now! He also said he got rid of the recirc assy too, still don't understand that one.
