Thanks guys. I probably just go with a quadrajet and spend the amazon gift card on something else.
The consensus seems to be that I should be looking for a carb with about 600 CFM but how does one calculate that? How can you find max RPM without a tach?
If you look at my previous posts some said that my 670 holley street avenger may be too much carb and bogging down the engine. The model is an 80670 double pumper. I believe it is vacuum secondaries. Could be that it needs to be rebuilt from sitting (it sat for some years) but the rebuild shop quoted me as much as it would cost to buy a new carb so I opted to get something better suited instead of rebuilding it.
As for seeing how my car runs, I posted a quick video showing what I mean about acceleration hesitation. When I come from a dead stop and steadily accelerate on the pedal, you'll notice a pause where the engine "cuts out" . I am not moving my foot off the gas or flooring it. Sometimes the engine will die if it stays in that period for too long.
