904 torque converter recommendations

I thought all 360 small blocks were externally balanced by the dampener ?
72 - 360 - larger unknown cam
B body - Convertible
294 gears - 8-3/4 rear end
So if that transmission came with a locking converter, you have to install a new one that locks ?
No the 72's didn't have a lock up. No lock up's until mid to late 80's.
