You will end up with a tired 4.3 with good heads. You will also need a spark plug factory and an oil refinery. If it's tired, it needs rebuilding. In my experience, it will suck oil like it's a pump.Why not do it right? You'll only end up there after you get tired of the smoke trail you'll leave behind.
