Default Custom Piston Size

I came accross this piston for sale, here are the specs:
15* LS1 head
4.14 Bore
3.75 Stroke
6.2 Rod
1.15 Compression Distance
-18.58 Dome Volume
.127 Inverted Dome

This is some crazy specs, anyone have any input? Ive been looking around for a 3.75 in crank but only found Callies. Just thought it was an odd stroke to go with, obviously custom specs. I calculated it out to be roughly 404ci.

Nice specs. Sounds like something I would do, but alittle longer Connecting rod and less stroke. Although I have used a 3.778 stroke once and the car almost went nines with it. Good crank size.
