1974 valiant stalls in gear 225 automatic

I have the same problem on my 1964 AP5 Slant 6. Ihave changed points,plugs,Put a kit through the Carby, checked all of the vacuum lines and have just changed the manifold gasket. I am out of ideas. Did any one come up with a reason for this problem. Appreciate any help


For various reasons , i have not done anything since . it has been driving ok , when i do drive it . I really think it is the timing . i just haven't got around to trying anything yet . My gut feeling is that advancing the timing would , likely fix the issue . when you changed the points , did you set the Dwell ? and , did you reset the timing ? changing points and dwell changes the timing .
