KB has 4340 billet main caps, 9/16 main studs and double 1/2 cross bolts and you prefer an indy block with 1/2 mains and cross bolt.


nope..sorry I just felt there was a lingering in the air that the others were obsolete. Maybe I jumped the gun.
As I recall from my 2015? KB block, the main studs are 5/8 thread, and 9/16 shank. Very stout, IMO.
