MSD Blaster 2. Brand new. Same issue with last coil. New ballast, new voltage regulator. Only thing stock is distributor. Going to replace that soon. Upgrading to electronic.

Also yes it progressively gets worse and worse as I continue driving. It hasn't shut off yet.

Trying the spacer and gasket today. I have a new MSD Blaster coil, new ballast resistor on firewall, new voltage regulator, and original distributor that it had when I bought the car. Problem existed with previous coil, ballast, and regulator. Will check fuel pressure.

If I give it VERY light throttle with foot on brake while in drive, the rough shaking idle will smooth out... would that be an indication of anything? Increasing idle speed does not achieve same affect.

I do not have a carb spacer... just a gasket and adapter plate. I can get a spacer and heat insulator gasket and see what that does.

The thing that confuses me most is. Why would the transmission shift from park harder at lower RPM when I'm having warm rough idle, than it would at a cold start with higher fast idle RPM? Shifts smooth first start up of day. Shifts hard when warm.

361/727. Power brakes yes, but I disconnected the brakes to eliminate that issue. Pretty much brand new Edelbrock 1411, I got it about 3-4 months ago. Choking the carburetor does not improve idle.

Been trying to get ideas on what people think this issue could be. I'm lost at this point. When cold. Car idles, shifts from park smooth, and runs well. When warm. Idles rough, engine shaking, shifts from park hard, performance loss. I don't understand what would cause that difference other...
