Fueling & Injection - Holley intank pump PN HLY-12-914

Anybody running a Holley intank fuel pump? Part number: HLY-12-914 its time for me to upgrade from a GM Performance 225lph pump to something bigger for the 402. I'm not looking for something bigger in particular but rather something better which will suit my needs with a moderate factor of saftey. 402 with great heads with a 238/240 Comp XER grind cam. I also want to run 150 dry shot with no problems. Lets be really conservative and say the engine makes 600 hp then add 150 for the dry nitrous. Anybody see any problems? How's the sound? I've heard some fuel pumps are really noisy. Any other recomendations?

The Holley is a Walbro 255 pump. It will feed a max of 600rwhp with the rest of the system stock. The pump is fairly quiet and will work great but I do not think alone it will be enough. Check out our fuel systems it will give you an idea of where you need to be.
