I was thinking it could be the wrong timing tab to, or maybe the the wrong balancer- I think you did get the piston at TDC, so it should be good. Without fully seeing the engine Im only guessing but I would double check the following-

Make sure there are no vaccum leaks- check the line that goes down to the vaccum modulator on the trans.

Double check your carb gasket, you need to have one of those big thick gaskets for a quadrajet. Dont use those real thin style they will leak.

Who did the tear down of the carb? You sure it was do right?

Is the carb spitting? what color is you exhaust- black- grey, wht, none?

Will the engine come up in the rpm's smoothly or is it chocking or stalling?
