So far I havent seen any fueling issues with my little 125 shot and hotcammed 4.8L. I recently got the idea of upping the shot to a 150 or so.. maybe 175? and fueling issues crossed my mind.

What fuel pump would you guys recommend for around 450-500rwhp?

What size injectors are the '02 4.8l motors equipped with, and would they be sufficient enough?

Any suggestions or advice?

thanks.

Yea I doubt you will be able to run that much with a cam and no fuel pump. I tried spraying my 150rwhp shot and I heard lots of detonation. I havent tried it with 1000 psi and I dont think I am goin to try. I was scared shitless when I heard the detonation that I dont want to do it again.
