318 Wont idle

I know there are many threads about this, and i feel like i have read them all and tried everything. So bear with me, and i apologize for yet another "my small block wont idle" thread.

So here is what i have and what i have done.

318 with electronic ignition, 3/4 cam, 360 heads, weiand intake, edelbrock 650. I drove the car about 10 years ago and it ran great, started great, idled great. Then it sat at my brothers shop for ~10 years. I got the car back, pulled the tank, cleaned it, new sending unit, blew out the lines, rebuilt the carb, changed the plugs, wires, distributor cap and rotor. She starts right up, runs at fast idle, but will not idle normal, will not idle in gear, and when i manage to get it moving she is way down on power. Since getting it started, i have pulled the carb back apart and rechecked the idle circuits and they seem clear to me, i have swapped two different ECU's into it, one of them being brand new, i have verified that i dont have any vacuum leaks, including using the ether test around carb base and intake to head gasket, i have put a new coil in, i have checked the gap inside the distributor, and i have checked that there is not any play in the timing chain. The timing was never messed with and the motor only has about 20k miles on it, as i built it in high school and know the mileage on both vehicles it has been in.

The only thing i can think is maybe there is something haywire with the distributor itself? but i have never messed with the distributors all that much, they have always worked when i put them in.

I dont think i have missed anything in regards to what i have done with the car, this is a 5 month long frustration and i am at a loss right now. Any help is extremely appreciated. Thanks.
