Clutch size on on gen 3 crate engine

Yes I am aware that you can use a 10.5 or 11” . My question is on a new 6.4 crate engine it comes with a flywheel and clutch. Need to know what size the engine comes with?

Sorry for trying to help. Maybe I could suggest a phone call to the company. It would probably be much faster than a forum post and more accurate.
