I have been thinking about a GM diesel for my next project. What I want is good power, a durable engine, ok mileage and no electronics. For this which is better, the 6.2L (N/a or turboed) or a 6.5L turbo? I have not been able to fine a good listing for the base power and power with a mild build on these engines. Thanks for any help. I got a membership to The Diesel Page but I can not find what I am looking for.
