If it's carbed I would check the floats...both the rise and drop heights.

Without actually being there to witness the problem and how the vehicle reacts I would agree with Kd5boc. I had a similar problem (usually stumble in acceleration or vehicle on incline or decline would cause flooding out) in a couple of vehicles it was the carb float. I would suspect in this case, given the age of the vehicle and assuming the carb was never rebuilt and the float was never changed to the brass type, the problem is the float. Quite a few of the GM OEM floats were made of some plastic material. (urethane I think) Over time they either absorb gasoline or somehow become as dense as gasoline and don't in fact float, they're kind of neutrally balanced. If I rebuild any carb and find this type of float I will replace it with a brass one.

Sounds like you need to adjust the carb. float level.

I recently had the same experience, except that my engine wanted to quit when I hit the brakes hard.

I checked the secondary float level and it was too high. Once I dropped the level the problem went away.

Does it typically stall if you have been sitting idling at a stop light? I would think the fuel level would be highest when you are at idle or near idle when the Power Valve is dumping fuel.

Check your power wire that goes to the distributor, your main battery cable, your alternator output wire, tach signal wire, etc. Make sure they are not being moved by centrifugal force. Either out of contact with what they should be in contact with, or into contact with something they're not.

My Nova used to occasionally shut down on right turns, & it turned out the battery cable was leaning over & contacting a header pipe, & the insulation melted through, causing an occasional big short. A similar thing happened when the big red alternator wire sank onto the exhaust crossover on the intake manifold.

My car would run great, thought I had some weak valve springs it would spit stumble at around 4800 RPM. It got where it would die when I put my foot to the floor. The problem was my coil wire running behind the throtle lever under the hood. It would rub it caused a short. Every time I would give it more than three quarters throtle it would short out the coil. Check for wires that could move and ground out when you turn left.
