Now I have read that some guys say to just screw out the throttle shaft screw. If so, that puts the engine at 450 without yet touching the fuel pump. This combined with a hp air filter system I am guessing will make another 25 hp. The truck that the engine is going into has a charge air cooler that will replace the aftercooler (using the intake from a n 14). The engine is going into a Freightliner FLD.Ĭan anyone answer what is a safe horsepower for a stock engine? The dual line feed is supposed to give about 25 hp. I am an extremely gentle driver (I will be the only driver of this truck), and I feel that if I up the horsepower I can get better mileage (being light on the pedal, driving by gauges). I have searched the internet and have not found the specific answers that I am looking for.įirst, let me say that the truck that I am talking about is a work truck. I have several questions about turning up a Big Cam 400.
