Unhappy backfiring 350v 5.7l man trans

Hi, went through process of finding tdc. Have timed eng at 8d btdc with vacumm plugged and hose plugged. When i hooked up the vac hose the timing changed TO advance. The eng starts but when i accel the carb backfires. Do i have to take out the dist and find tdc again.

thanks in advance
