I have a 71 C/20 with the original 307. It sat for twenty years inside a grain elevator building before I bought it. After rebuilding the two barrel carb and installing a HEI the engine runs like a sewing machine. Does not smoke or burn a drop of oil in 3000 miles. I believe the 307 receives bad reviews because the 350 is so much more common today. It’s also very easy on fuel. I use the truck strictly for bringing in fire wood. The low first gear in the original four speed is perfect when it’s loaded with wood.
