    Fuel Pump

    First off I dont know if this should be in here or the genral help, but I went with my gut on this one.

    What would you guys think would be the max injectors the stock fuel pump could handle? I will be getting some 42's and I dont know if I need to get a new pump. Just wondering.

    Right now the car is mainly stock with an slp lid, LT and ORY (from previouse owner) The new parts are on their way and they include; cam 235/243 .621/.624 111LSA, PRC 215CC Heads and a Fast 92/92, plus all supporting mods (ie ls6 oil pump, ls2 timing set ect...) I talked to my dyno guy that has been working with LSX's for awhile and he told me that 38 Ibs injectors would just be a hair too small for my set up and suggested the 42 just to be on the safe side. I forgot to ask him about if the fuel pump would be able to handle it. So was just looking to see if it would be worth it to buy the 'better' fuel pump or keep the stock one.

    if your already spending that kind of money i would just get a racetronix fuel pump there are like $200 something and well worth it.
