My 1985 c30 with a small block 350 is sputtering/stalling when driving. It was worse then I replaced the fuel filter with a less restrictive one. The stalling isn’t as bad now but I was wondering if it could be the electrical system. It used to stall completely when I would stop and try to go again. But now it doesn’t do that anymore. On my test drive it only did this once but it sputtered when accelerating. I hear a click sound and it fires right up again on its own and continues. I do have a video but I don’t know how to attach it.

Before you replace any more parts. Check your basics,vacuum hose routing and condition. Make sure the vacuum advance cannister is functioning. Check timing. Inspect cap,plugs,and wires.

what is the temperature outside while driving, could be a vaper lock situation, I've been dealing with that here in AZ. I'm in the process of adding a vaper release filter

Checked the vacuum hoses and all that and everything is good, I’m in AZ as well but i usually drive it in the evening and then it’s about 80 degrees give or take. At the moment i have a rubber fuel line from pump to carburetor. My buddy used to have the same problem then switched to a shorter run hard line. Could that be a solution.
