Waterthunder, What is a ballpark price for an LS6 engine from GM? Also, do you think a hurricane Katrina flooded car with one in it would be salvagable. There is a yard not far from the house that has thousands of cars, trucks, motorcycles that were towed out of New Orleans that can be bidded on. Seems like a rebuild would fix all issues on an aluminum engine. Can you run a carb on these things or do you have to use fuel injection?
