Bought my truck over the summer been driving it everyday and love it. I was thinking about it earlier today and decided i need to do alittle tune up. What i was thinking was doing an oil change, changing filters (air, oil, fuel, etc.), and change spark plugs. Its a 460 and its got about 204,150 miles on it. What kind of oil should i use? And whats the best spark plug for a big block 460? Any other ideas while im doing all of this is also appreciated.
