Steve,
New cap and rotor and verified/corrected mag pickup distance from stator. I did verify correct wiring order but will do that again. Not a new coil ( MSD Blaster) or plug wires( MSD 8.5). I did not adjust idle mixture screws from Cliff setting after installing the Quadrajet. I did rebuild the Edelbrock heads, ported/ polished, new viton seals and lapped each valve but did not check spring pressure.
I will go through your suggestions one at a time
