Keith doesn't put Scat cast cranks ($695) in all his stroker motors; those with the cash put in a billet ($2495), which is much stronger.
Steve, I'll definitely admit my math could be wrong, as this sort of thing gets pretty fuzzy for me. It still seems to me that you want to move the centroid of the journal up, not down, to increase stroke. However, I'll give it some more thought after the smoke stops coming out of my ears and possibly understand your explanation. As to the Scat crank, I've already got one in my 496. If money (and value) were no object, I'd have a billet stroker instead for the increased strength. I won't take my engine above 5700 with the cast crank, it's the weak link. I came up with this possible idea in my quest for a forged crank, much stronger than a cast one, and cheaper than a billet.
Thanks to all,
Dan
