While my 414 has a real rough idle it is smoother and quieter when cruising due to being balanced and a properly matched combo. I also run a 2500 stall converter and it does not need more than that. Go back to stock stroke? Not me. I would cam your stroker for street manners if that is what you want. Then you will have the torque of a stroker with the mild manners you are seeking. For a street car a stroker is the way to go. Torque to get that heavy car off the line without the need for big gears, big converters, or big cams.
