Specified dwell angle is 28 - 32 degrees for all the first gen Firebird V-8s. Cam selection will not affect the dwell angle, nor does it affect the initial timing recommendation of 9 degrees BTDC, except for the RA IV. What does change is the distributor advance curves, both centrifugal and vacuum advance. You will need to tailor your distributor for your combination.
