Is this cam a stupid idea?

And KB107's piston+pin weights are only 8 grams heavier than the IC741's mentioned in the article above, so are another option. I assume the assertion that the IC741 piston+pin weight is the same as stock is true, as mentioned in the article. (I always have trouble finding info on stock 5.9L Magnum piston+pin weights....I'm gonna have to write it down someday.)
Verrry interesting. They're a hell of a lot cheaper than the Icons... Maybe a few grams could be shaved off even?
Just read a post on here where a guy measured stock bore 5.9 piston weighed 469 grams, pin was 135 grams, and ring set was 39 grams.
