-Due to overall slower piston speeds per rpm.
-The longer connecting rod is cause,for less loading on both itself and the piston.
-Smaller combustion chambers coupled with the shortest stroke create more efficient combustion process.
-The piston has either the or one the thickest ringland out of the ls family.
-Crankshaft is inheritly stronger due to the short stroke while being cast of the same material.
-Less crankshaft deflection once again due to the shorter stroke same material.
I could probably think of more but,I dont think its warranted.

That is pretty cool. When I first heard about this article I was a little shocked that there was no valve float and no top end problems but I see they did make some mods to the top end of the engine. Cool info, and pretty neat little set-up. I'd like to see what it woulda made with stock intake and non ported heads.

Excellent write up thanks for sharing!
Was there a dyno graph by chance, I'd really like to see the TQ numbers and what rpm ranges they were working in. I'd like to see how much the shorter stroke would have on the low rpm torque production. I'm not a huge fan of high stalls, not what I'd like to drive daily.
Thanks again!
