I am planning to remove the carb and hopefully I can find the right number to buy a rebuild kit. I will also remove the tank and clean it myself or have somone else (radiator shop) do it. The tank need cleaned whether I keep the 230 or put in a 350. This truck has been sitting for at least 6 years. I will also perform a compression test. I removed one of the plugs to match it with the right compression tester and noticed that the inside is as dark and oily as the outside of my motor. The plug was covered with black. I have heard that when engines sit oil seeps down on top of the cylinders. How long would it take to burn this oil out? I can buy a 65 long bed for $1000 that has a running 327 two barrel, a good seat and two chrome bumpers. It is looking better and better as a parts truck.
