Default 66 gto charging issues

Hi all, i recently had a dead battery so went through the obvious fixes. Car wouldnt run when taking off the neg. cable from battery.
Replaced alternator with a powermaster 60 amp i believe.
Still wouldnt run when taking off the cable. Replaced voltage regulator with a delco brand. Same issue. Seems to charge the battery, im getting 12.5 volts but no more when its running. Turned on the headlights and dropped to 11.9 volts but seems okay, not getting anything more to the battery than 12.5 volts even when revving. What am i missing. Neil O
