After warming the engine up, I can drive total 8-10 miles fine before the engine begins to buck and skip... During the bucking and skipping, if I put my foot on the gas it accelerates for a moment and goes back to bucking and stalls if I repeat to press the gas to keep it started...

Another scenario, if I let it coast for a moment without giving it gas and then press the gas pedal, it drives normally for about another 8-10 miles before it bucks and skips again...

If it stalls, I'm able to start it right back up... Fuel PSI at the carb is 8-9 psi. Carb is an Edelbrock 1405 600 cfm and an Edelbrock single plane intake.

Posted something similar in a Facebook group and didn't get very many responses, but a guy did mention something about the possibility of my fuel bowl being clogged or the fuel/air ratio screws holes are clogged and to remove the top end of the carburetor and inspect these parts including the floaters...

Sound about right ? Or should I be looking for something else ?

Another note: Seems like a lack of power...

1st gear take off seems a little slow and I'm not able to burn rubber... If I attempt to spin the tires while holding the brake in Drive it revs but no tire spinning, and as soon as I let off the gas pedal it stalls... Or maybe I'm not doing it right ? 🤷🏾‍♂😂

Well, I'll tell you this. MAX recommended fuel pressure from edelbrock is 6 to 6.5psi. So your pressure is too high, and they get wicked touchy at the top end of that range. You're about 50% above the manufacturer specs.

I'm going to run another pressure test to double check that fuel pressure. I'm using a fuel pump pressure/vacuum gauge tester to test the fuel pressure. I'll be connecting the gauge to the end of the fuel hose connected to the carburetor, to the the fuel pressure as the fuel is entering the carburetor. The engine is at operating temperature.

Take that single plane intake off of there. get a good dual plane and cut the divider 1 inch deep 1 inch long towards the back where the secondaries are.
If you can try and find a old Weiand stealth dual plane like this

That one is on Ebay right now and you need a regulator as stated before , Edels don't tolerate high fuel pressure like a Q jet will.
