I had this exact same problem with a 1973 Javalin. I changed the oil and filter. I used 4 quarts of 10w-40 regular motor oil, and two containers of STP (total 5 quarts) and the problem cleared right up. I drove the car for years like this and everything worked fine. I finally tore the motor down for a rebuild and found the main and rod bearings were worn. I'll bet you have the same problem.
