Car runs great , no flat spots but doesn't have that smooth idle that I would expect from an all stock freshly rebuilt 292. No vacume leaks, all new ignition components, properly adjusted valves and a pertronics ignition, timing & idle speed within spec and the choke cycles properly.

I was expecting an idle like that of a bone stock 289 or 390....don't get me wrong it doesn't sputter or shake your teeth out it just isn't as smooth (especially in gear) as I feel it should be. This is my first Y block and my introduction to the Holley 4000 teapot.... are they bad idlers ?
