Question: Best Fuel pressure for LT4

[wingnut96lt4]

​Guys what is the best fuel pressure of my LT4 ?I talked to some one who said if I raise the pressure Maybe 4 or 5 Lbs it will increase the Horsepower 5 to 10 . TRUE Maybe not that much, I think it should be about 37 38 lbs stock. Does it come with an adjustable pressure pump OR fixed ? I will get an adjustable one if needed. Should be about 42 43 I think. Any thoughts ??:ugh

Stop talking to them. They lack knowledge.

Nominal fuel pressure for the 1G LT4 is: 41-47 psi. Adding pressure just makes the engine run rich.
