stock pump and 42 lb injectors is just like wasting your money. you can put 42lbers on there and you wont have a problem at all but to be effiecent for anything you should upgrade to a 255 racetronix pump.

FUEL REQUIREMENTS
Typically, at wide open throttle, full power, an engine requires 0.5 lbs. of fuel per horsepower every hour. A gallon of gasoline weighs approximately 6 lbs. Therefore an engine rated at 350 horsepower will require about 175 pounds (29 gallons) of fuel every hour.
(350HP x .5 lbs = 175 lbs of fuel 175 lbs/6 lbs = 29 gallons per hour)

The math is evidently faulty. Remember, they are trying to sell injectors and fuel pumps. I put a new gauge sender & pump assy, straight from the GM dealer, in mine two years ago. Your old pump was dead, not too small.
