If this is true then it begs a couple questions...

1. Why do the SS racers run them?

2. Why did they require weight added on both ends of the crank to get them to balance with the same rods and pistons as a forged crank?

Maybe it's only 1/2 pound and the less weight is worth it like a thousand other tiny seemingly insignificant things the SS racers do.

I am not causing global warming, I am just trying to hold off a impending Ice Age!
