FE 360 not staying running
75 ford
started with 2 Barrel Carb
Upgraded to a 4 Barrel Edlebrock on holley 600
The truck ran fine for the previous weeks.
One night it stumbled going up hill, and it started from there.
Its started fine and runs for 30seconds, and then it stumbles to a idle and dies.
I replaced the Ignition Coil Module, Ignition Coil, ignition cap inside distributor.
The last time i looked at the plugs they looked quite decent without fouling.
Im stumped on why this thing is not running properly.
The next thing i will do is replace the spark plug and set my timing so it doesn't run as rich.

So it idles for a while and then stumbles and dies? Mine did that for a while, only would die if idling, was fine at even 100rpm above idle. Problem was gone when I filled the tank with fresh gas.

How is your fuel pump?

The carb I have was jetted to run a modded 360, but this problem hasn't happened before to warrant changing the jets?

Carbs have idle screws as well as jets to adjust the mixture. Not sure what the adjustment procedure is with a Holley though. The idle screws may have backed out, causing your mixture to be really rich.

On my Holley, there was two idle mixture screws, one on each side of the bowl. They are very small flat head screws. If I remember, you would turn them all the way in and then back them out 1 and 1/2 turns. This would usually be good enough to run. Then I believe you Turn them out or in together in 1/2 turn increments to achieve the best idle. You might have to adjust your idle speed screw as your idle speed may have changed after that.

I would re-check all the coil wiring. In the third picture from the top, you have two wires on the coil half-azzed twisted together. Could be a problem of the coil not getting consistent voltage.
Then go on and troubleshoot from there
