Peep this article about increasing displacement for the LS to 455ci:

DAMN. That's a lot of motor at 385lbs. The rod ratio is a terrible 1.46 but it'd be pretty cool for a while. The 427 version is a more exceptable 1.53 similar to the 454. The low-end torque must be wicked with ratios like that!

They mention the bore/stroke ratio a couple times. Does anybody know what the significance of this ratio is? Does it have something to do with valve shrouding?

It would be real interesting to see what it could do in the 1/4, if they could keep traction that is.
