I like a vacuum advance on a street driven car for better part throttle cruise and fuel economy and have always used them. Other hot rodders leave them out and take the economy hit. Some swear there's no difference. The one with the vacuum (the one I used) comes with a lock out adapter if you don't want to use the vacuum. Little plastic piece you screw in. Your option either way.
