I recently purchased a 56 Mercury Montclair with a 312 and carter 4b.



My first question is since the distributer has vacuum advance do I have to switch to a 57 and up to mount an edlebrock carb? I already know ill need and adapter for the manifold.



Also the right side of the car throws a lot of white nasty smoke when it warms up. I was told valve seals are common problems on y blocks. Has anyone had this problem?
