Flywheel/Clutch Size in the OD transmission

He has a slant to use with the 833OD and said he was gonna run the slant for awhile then swap to a 318. He's got both OD bellhousings. So what size flywheel is used with each motor/bellhousing. I would have thought they would have been using a 10" for both by then.
I thought the slants and 273's used the 122 tooth and the 318 340 and 360 used the 130 tooth ?? but its the bellhousing that dictates flywheel size ,I believe.
