Default Ground or Power Problem

My 87 has some type of either ground or main power problem.
When the engine is running (vibration ?) the interior light, dash, headlights, all electrics will blink once in a while. When this happens the engine also misses for a brief second.

The previous owner had the engine out last winter for a rebuild. My guess is he did not tighten either a Ground or Power feed. All battery connections are clean and tight.

Of course there are many grounds and power feed points. In a effort to make this as easy as possible, my question.

Is there a main ground or power feed that could/would effect all electrics in the car ? Where would you head first ?

Thanks
8Valve

Check the ground on the block just above and in front of the oil filter. Be sure its clean and tight.
