Depends on the model, it would have to be one that uses a throttle plate or tuned intake in order to create significant vacuum. Certain years with 617 engine had these, and all the n/a 606's. Probably others too that I'm not familiar with. Anyways, old timers used vacuum gauges to train the driver for fuel economy.
