I have a 73 challenger with a 440 and a single plane intake the engine turns over but really rough. I don’t really have time too take the spark plugs out so I’m wondering if I can just pour some oil down the intake manifold and turn the motor over to get it in the cylanders
You know what lubricates the cylinder well? Running the engine, why don’t you just start it? If the engine turns over rough I don’t think oil in the cylinders will help
