| The stock injectors on a 3800 really are not that great for higher horsepower builds. There is a little bit of headroom with the L67 injectors, but once you start using a turbo or a small supercharger pulley you will start to exceed the capabilities of the stock injectors. | The stock injectors on a 3800 really are not that great for higher horsepower builds.

| Every fuel pump's performance will vary based on base fuel pressure and voltage supplied so **take these numbers with a grain of salt**. In general this is a good outline of a safe fuel pump size for the amount of power you're trying to make: | Every fuel pump's performance will vary based on base fuel pressure and voltage supplied so **take these numbers with a grain of salt**.
