Looking for some help on the valve settings on a 1966 427cid/425hp, what would the settings be cold for the intake and exhaust.    Thanks   Geof

Service manual says .024 for intake and .028 for exhaust with engine at operating temperature. You can set them about .004 tighter cold to get the motor started. Then once you have the motor started and warmed up go back and set them at the spec. You could just set one at the spec warm, then let it sit overnight to cool down and check it again, that will tell you what the cold setting should be and you can go ahead and set them all.
