I have a 1987 FSB. It has the 351w. It isnt EFI it has the carb. I did away with all of the emission stuff. Plugged the thermactors and the egr port on the manifold. The only thing I need vaccum for is the brake booster, auto tranny, and heater controls.The distributor os a mechanical advance.Where do I plumb the vaccum from the intake to? does it go to the booster? Does it go to the carb. How should I plumb this thing for vaccum?
