On your 69 500's, what are most of you doing with the smog pump? Are you restoring everything and making it fully functional, or deleting this item from the engine. And if restoring it, who do you recommend to restore it?
If your doing a restoration then your putting it and everything else thermactor back on the car. If your modifying the car then its your choice.
From there some choose (in some states you don't have a choice legally if your going to drive) making everything operations. Some choose to plug the manifolds and gut the pump.
