What would it take to make 1.44 lbs-ft per cid ?

Really? Read the room. This thread was about NA Smallblock TQ PER CUBIC INCH of power production. This is about using atmospheric pressure to overfill the cylinders to achieve above average efficiency.
I don't think anyone's arguing that adding positive manifold pressure won't make outrageous tq/ci.

What do you think a locomotives V16 diesel-electric produces?
Is that an example of a "bunch of torque"? Sarcasm, if you can't tell. See how your post actually takes away and contributes only confusion to possibly those trying to learn? J.Rob
Who says so? Not the thread title.
