They were not making anywhere close to 1500HP back then.

Isn't that the same source that told you SD 455 rod crack if you look at them right?

Let's review the facts;

The guy that has the sole rights and a garage full (literally) of new aftermarket cast crankshafts says the factory cranks suck.

The guy that has the deep deal on aftermarket rods, says the best factory forged rods suck.

Things that make you go hmmmm


Also I doubt you know how much prep work has been done to KK's crankshaft. I'm willing to bet SCAT wouldn't recognize it as one of their own upon an initial visual inspection.
