It wouldn't kill you to use a turbo, would it? You could realize much higher output numbers with the same amount of fuel without ever going into positive boost w/ a turbo, just keeping it away from fully spooling, so that it keeps the engine running as though it were getting 100% VE as often as possible.

BTW - if you want something that will get you decent mileage, and will bolt into your truck with a simple mount kit - Olds 307 Diesel engine.
