At that price, it’s really costing way to much (for me anyway) for the extra 30 cubes.
Think that money would be better spent on other things.
At $1800, + $1400 for the rods it would be something I would consider.
As Wconley pointed out, even using a standard 6.7 rod, start running out of room for the piston.
The piston pulling out of the bore at the bottom is something I would definitely not want. The LS guys run into that, severely limits the engine life if they go too far on the stroke.
