If you want gas mileage, you need to build a stock of motor as possible then use a power adder.

+1 on this. Unless you can afford to DD a 408 that is getting single digit MPG then building up a stock motor then doing some sort of SC or turbo on it.

stock motor and a turbo would be the best way to keep economy then.
