This is why most of the stockish rebuilt 340/383/440's I have worked on can't get out of their own way. Its a stockish build so everyone figures its not worth 15hp or whatever HitRod picked up in their latest cam timing article. When it makes 200hp and can't bark the tires everyone blames the poor old engine. Glad you found a smoking gun. Now put the wheel to it before you button it back up!
