I have an original service manual but did not know it had that info in it. Thought you were displaying info from some special manual. Guess I should look more at it. No telling what I have missed and done things the hard way. Bob built my radiator as well from an original thus the cast iron pump. This was two fold. Pump for more clearance as well. Problem is I used the timing cover for a 70 or later. This was due to having a 70 model crank so needed some scale to time to. Could have used early timing cover but moved the other way. Was a difficult decision but do not regret it...........yet. That fan should pull some air with that pitch.
