Timing??
Never had a cam that was cut with 4 degree advance before. Should i still be setting the total timing to 32 degree?? Only ask because im having a hesitation when i press on the gas to fast and at high rpm the engine acts like its missing or starving. Have new plugs, wires, distrib and 750 EB carb. new fuel pump.

"If it RUNS good, it IS good". And conversely, if it DOESN'T run good, it ISN'T good.
We call this "tuning". You adjust whatever facilities you have available for adjustment, until they're the best they can be. Once you do that they're as much like they "should" be as you're ever going to get them.

Re: Timing??
4 degrees advance is pretty common for aftermarket cams. The other cam specs (duration and LSA) will have a bigger impact on the ignition timing. As Sofa stated, test it and see. My guess is that this is the Ebrock carb giving you issues. If you tell us more about the setup and symptoms, we might be able to help.

Re: Timing??
"4 degrees advance" refers to valve timing. It has nothing to do with where to set your ignition timing (beyond tuning optimization, as mentioned above).
