318 Engine stumble

I know it’s been a while.

To update this some. I have not had a lot of time to work on the car.
I did change the distributor to the skip white gym hei style distributor.
I set the base timing to 16°.

The spark is much hotter and the vacuum advance is operational where the points distributor advance was frozen. At first the car still had the hesitation but I could drive it.

Now it Revs up fine
I put it in gear.....and....
It dies as soon as I give it any gas. It won’t even move a foot
