about any standard trans smallblock flywheel from 55 on that takes an 11" clutch [truck] will work - there's a car bellhouse and flywheel that's smaller and mount the starter different, and that's for a 10"

for the balance, as above - if you get it surfaced at a machine shop they'll check the balance, otherwise it's not a worry
