I am looking for increased fuel economy and not horse power, all though a little horsepower wont hurt.:LOL: I would like to keep every thing as "stock" as possible since this a daily driver.
Since I am planning a rebuild would it be a good idea to install vortec heads while keeping everything as "stock" as possible?
Or, since fuel economy is my main goal rebuild what i have and use a stock or RV cam? Aluminum intake?:confused:
